Add width support to the width of the wifi channel

Tested on my laptop and OpenWRT Linksys I have now

Thanks for the addition and sorry for the delay, but there are a couple of issues.

According to line #420 in https://git.kernel.org/pub/scm/linux/kernel/git/jberg/iw.git/tree/interface.c#n420 the width may not always be present. This can be handled by wrapping it in non-capturing optional group. Then the width key returned by match.groupdict() needs to be checked if it is None before casting to int.

The test cases for IwDeviceParser in tests/test_iw_device_parser.py also need to be updated by adding a width key with a corresponding value in the expected_data dict since the data returned by IwDeviceParser.parse() is changed.

Hey,
Thanks for the code chances, committed.

huh, looks like the tests failed - is it comparing to a dict without the width?

Yes, the tests need to be updated as well. I mentioned it in my comment above because GitHub doesn't support suggesting changes in unmodified files.
