The new streaming Reader/Writer/Protocol interfaces will be experimented on in the streamdev branch. The interfaces will be made private for now to disallow custom implementations.

This release v1.28.0, which includes a series of changes cherry-picked from
`dev`. It skips the following changes that are currently on dev:

- #485, #486, #488: These are part of the streaming changes that are still in
  progress in the streamdev branch and should not be released without the rest
  of those changes.
- #507, #508: These changes by @jparise record and expose column numbers for
  AST identities. These cannot be released without #522, which is not yet
  ready.

Besides that, all changes from dev are included in this change.

Here's an API comparison between the last release (v1.27.0) and this release,
generated with the help of apidiff.

```
--- go.uber.org/thriftrw/ast ---
Compatible changes:
- Field.IDUnset: added
- Pos: added
- Position: added
--- go.uber.org/thriftrw/gen ---
Compatible changes:
- GeneratorOptions.EnumTextMarshalStrict: added
- Options.EnumTextMarshalStrict: added
--- go.uber.org/thriftrw/gen/internal/tests/enum-text-marshal-strict ---
NEW PACKAGE
--- go.uber.org/thriftrw/idl ---
Compatible changes:
- Config: added
- Error: added
- Info: added
- ParseError: added
--- go.uber.org/thriftrw/idl/internal ---
Incompatible changes:
- Parse: changed from func([]byte) (*go.uber.org/thriftrw/ast.Program, error) to func([]byte) (ParseResult, []ParseError)
Compatible changes:
- NodePositions: added
- ParseError: added
- ParseResult: added
--- go.uber.org/thriftrw/version ---
Incompatible changes:
- Version: value changed from "1.27.0" to "1.28.0"
```

Of the two incompatible changes:

- One is the version number change. This is desirable.
- The other is an internal API. This is safe.
