Thanks. Could you send a pull request?

@parrt Hello, I did the PR for this issue: #19. Can you look at it? Thanks

antlr4 python is unusable again because there's an outage with https://status.maven.org/ (and would still be the case if central.sonatype.com/ went down).

This should be a soft failure with antlr4, warning instead of erroring out.
--help and --version should work even if maven is down, and we also should have a --skip-version-check cmdline option.

I started to fix this, then realised TimeoutError is already added and committed[1] but not released. So currently, users via pip will see:

...
           ^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/opt/homebrew/Cellar/[email protected]/3.12.5/Frameworks/Python.framework/Versions/3.12/lib/python3.12/ssl.py", line 1104, in read
    return self._sslobj.read(len, buffer)
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
TimeoutError: The read operation timed out

instead of

Could not get latest version number, attempting to fall back to latest downloaded version...
Found version '4.13.2', this version may be out of date

Could we get an updated release on pip please? This would fix this issue and antlr/antlr4#4703
