Bug in fieldnames list

[matthewfeickert]

Woops. Looks like there's a bug here

pylhe/src/pylhe/__init__.py

Line 251 in 7519967

fieldnames = ["initInfo", "procInfo" "weightgroup", "LHEVersion"]

as of PR #233.

We should add a test to catch this and make a patch release.

@matthewfeickert Yes, it should be fixed, but does it have any implications? I think not since tests passed using the self["weightgroup"] dict way. I know that the __all__ variable is tested somehow (either pre-commit or ci).
