[Heap] Change value of minimum or maximum element #116

Adds two methods to change either the minimum or maximum element of a Heap instance. If the value changes enough that the previous second-place element now surpasses it, that former second-place element will take over for the heap's min/max element.

For testing purposes, I needed a way to precisely define a heap's pre-test state. Therefore, I also added a new initializer that receives an exact storage layout as input. It's a fail-able initializer. This requires a testing function. There is such a procedure locked in the debug-only invariant code. I moved that code to a new unconditional method that both the new initializer and the invariant-test code both reference.

The replaceMin and replaceMax members look like good additions to me. BTW, do you have motivating example for adding these? It's not immediately obvious to me that these operations would often come handy in practice. (It would also be nice to list heap implementations in other languages that provide similar operations.)

I strongly object to introducing _someHeapViolation -- I think that part of this change needs to be reverted, and the public init(raw:) replaced with an underscored & _spi(Testing) initializer.

This is a far simpler case than the general bubbleUp. I think would be beneficial to replace this with a direct conditional swapAt:

Suggested change
handle.bubbleUp(maxNode) // This must happen first
if handle[maxNode] < handle[.root] {
handle.swapAt(maxNode, .root)
}

(Untested)

It's not immediately obvious to me that these operations would often come handy in practice. (It would also be nice to list heap implementations in other languages that provide similar operations.)

This was one of the future directions from the original Heap authors. It makes sense because naïve replacement via a pop and push unnecessarily does two rounds of element shuffling instead of one. (And maybe a reallocation too.)

Remove the initializer's own unit tests, assuming that it will always work instead.
If the format of the incoming data does not match that of a heap, a precondition error is flagged instead.

…v1.1.0 (#906)

| Package | Type | Update | Change |

| http_archive | minor | `1.0.6` -> `1.1.0` |

### Release Notes

<details>
<summary>apple/swift-collections
(com_github_apple_swift_collections)</summary>

###
[`v1.1.0`](https://togithub.com/apple/swift-collections/releases/tag/1.1.0):
Swift Collections 1.1.0

[Compare
Source](https://togithub.com/apple/swift-collections/compare/1.0.6...1.1.0)

This feature release adds a number of new data structure
implementations, along with minor changes to existing constructs.

##### New Data Structures

- `Heap` implements a min-max heap, backed by a native array.
(Contributed by [@&#8203;AquaGeek](https://togithub.com/AquaGeek))
- `BitSet` and `BitArray` are two alternate representations of a bitmap
type, backed by dynamically allocated storage. (Contributed by
[@&#8203;MahanazAtiqullah](https://togithub.com/MahanazAtiqullah))
- `TreeSet` and `TreeDictionary` are hashed collections implementing
Compressed Hash-Array Mapped Prefix Trees (CHAMP). They provide similar
API as `Set`/`Dictionary` in the Standard Library, but as persistent
data structures, supporting incremental mutations of shared instances
and efficient structural diffing. (Contributed by
[@&#8203;msteindorfer](https://togithub.com/msteindorfer))

##### Other Changes

- This version of the package can only be built using Swift 5.7 or
later.
- New methods: the `OrderedSet.isEqualSet` family of functions provide a
way to test that two containers contain the same members, ignoring the
order of elements.
([https://github.com/apple/swift-collections/issues/183](https://togithub.com/apple/swift-collections/issues/183),
[https://github.com/apple/swift-collections/pull/234](https://togithub.com/apple/swift-collections/pull/234))
- New method: `OrderedSet.filter` implements a version of the standard
filter operation that returns an `OrderedSet` instead of an `Array`.
([https://github.com/apple/swift-collections/pull/159](https://togithub.com/apple/swift-collections/pull/159))
- `debugDescription` implementations have been updated to follow Swift
best practice. (These are called by container types like `Array` to
print their elements, so they work best when they're succinct variants
of `description` that are suitable for embedding in structured output:
specifically, they must not produce unpaired delimiter characters
(`[`/`]`, `(`/`)`, `{`/`}`, `<`/`>` etc), raw top level commas,
semicolons, colons, unquoted strings etc. `debugDescription` should not
needlessly print type names etc.)
