⚠ BREAKING CHANGES

• This PR changes the definition of grouping sets in
  AggregateRel to consist of references into a list of grouping
  expressions instead of consisting of expressions directly.

With the previous definition, consumers had to deduplicate the
expressions in the grouping sets in order to execute the query or even
derive the output schema (which is problematic, as explained below).
With this change, the responsibility of deduplicating expressions is now
on the producer. Concretely, consumers are now expected to be simpler:
The list of grouping expressions immediately provides the information
needed to derive the output schema and the list of grouping sets
explicitly and unambiguously provides the equality of grouping
expressions. Producers now have to specify the grouping sets explicitly.
If their internal representation of grouping sets consists of full
grouping expressions (rather than references), then they must
deduplicate these expressions according to their internal notion of
expression equality in order to produce grouping sets consisting of
references to these deduplicated expressions.

If the previous format is desired, it can be obtained from the new
format by (1) deduplicating the grouping expressions (according to the
previously applicable definition of expression equality), (2)
re-establishing the duplicates using the emit clause, and (3)
"dereferencing" the references in the grouping sets, i.e., by replacing
each reference in the grouping sets with the expression it refers to.

The previous version was problematic because it required the consumers
to deduplicate the expressions from the grouping sets. This, in turn,
requires to parse and understand 100% of these expression even in cases
where that understanding is otherwise optional, which is in opposition
to the general philosophy of allowing for simple-minded consumers. The
new version avoids that problem and, thus, allows consumers to be

v0.54.0

0.54.0 (2024-08-11)

⚠ BREAKING CHANGES

• The encoding of IntervalDay literals has changed in a
  strictly backwards incompatible way. However, the logical meaning across
  encoding is maintained using a oneof. Moving a field into a oneof makes
  unset/set to zero unclear with older messages but the fields are defined
  such that the logical meaning of the two is indistinct. If neither
  microseconds nor precision is set, the value can be considered a
  precision 6 value. If you aren't using IntervalDay type, you will not
  need to make any changes.
• TypeExpression and Parameterized type protobufs (used
  to serialize output derivation) are updated to match the now compound
  nature of IntervalDay. If you use protobuf to serialize output
  derivation that refer to IntervalDay type, you will need to rework that
  logic.
• JoinRel's type enum now has LEFT_SINGLE
  instead of SINGLE. Similarly there is now LEFT_ANTI and LEFT_SEMI.
  Other values are available in all join type enums. This affects JSON and
  text formats only (binary plans -- the interoperable part of Substrait --
  will still be compatible before and after this change).
