This PR adds Python 3.11 support.

Closes #88.

Description

Transformer doesn't work in Python 3.11, due to breaking changes in dataclasses (python/cpython#99401). Namely, the default values for dataclass fields must be hashable. In the Transformer codebase, MappingProxyType is used, which isn't hashable. This PR fixes those issues, by using default_factory to get around this issue.

Types of Changes

What types of changes does your code introduce? Keep the ones that apply:

  • Bug fix (non-breaking change which fixes an issue)

Review

Reviewers' checklist:

  • If this PR implements new flows or changes existing ones, are there
    good tests for these flows?
    If this PR rather removes flows, are the obsolete tests removed as well?
  • Is the documentation still up-to-date and exhaustive? This covers both
    technical (in source files) and functional (under docs/) documentation.
  • Is the changelog updated?
  • Does the new version number correspond to the actual changes from this PR?
    In doubt, refer to https://semver.org.
