Release new version

[jahway603]

There have been many commits since https://github.com/bitcraft/pytmx/releases/tag/v3.31 released on Dec 1, 2021. Can you please release a new version?

Seconded, TiledMap.get_layer_by_name's type hinting still says it returns an int even though it's actually returning a layer and that fix was applied a year and a half ago

Upvote, the version is defined inside git but not released in PyPI, could you please release it?
Thank you
