- Enable oneof_enum test case that passes now (removed the xfail)
- Switch from toml to tomlkit as a dev dep for better toml support
- upgrade poethepoet to latest stable release
- use full table format for poe tasks to avoid long lines in pyproject.toml
- remove redundant _WrappedMessage class
- fix various Mypy warnings

This means the betterproto plugin no longer needs to depend durectly on
protobuf.
This requires a small runtime hack to monkey patch some google types to
get around the fact that the compiler uses proto2, but betterproto
expects proto3.
Also:
- regenerate google.protobuf package
- fix a regex bug in the logic for determining whether to use a google
wrapper type.
- fix a bug causing comments to get mixed up when multiple proto files
generate code into a single python module
