add option to specify baudrate

[semininja]

added argument to __init__ to allow users to set baudrate if desired

retains previous default if unspecified

I don't know enough about how the CI checks work to be able to tell why black is somehow causing this to fail; it doesn't appear that the actual function was tested.

Good addition, thanks for the PR!

Sorry, I meant to respond to your followup about black. If you run pre-commit, it should reformat things accordingly so it will pass if you submit the changes it makes. You can find information on using pre-commit here:

Unfortunately, I'm not able to run pre-commit successfully for some reason. Here's what appears to be the relevant chunk from the log:

      _ruamel_yaml.c:6:10: fatal error: Python.h: No such file or directory
          6 | #include "Python.h"
            |          ^~~~~~~~~~
      compilation terminated.
      error: command '/usr/bin/gcc' failed with exit code 1
      [end of output]

  note: This error originates from a subprocess, and is likely not a problem with pip.
error: legacy-install-failure

× Encountered error while trying to install package.

Looks like it was an extra bit of whitespace causing the issue. Thanks!
