Do not exclude buttonless devices that have axes

[StelardActek]

Changes to groups.py to enable devices such as racing pedals (which have multiple axes but no buttons) to be remapped in the GUI.

Thanks a bunch. Can you please check the failed test?

Let me know if you need help running them locally, the test setup is somewhat dreadful, and pycharm does not like it. See https://github.com/sezanzeb/input-remapper/blob/main/readme/development.md#automated-tests

Hey @sezanzeb, I'll do my best but I'm not actually a python dev so I'm not really familiar with how these things are done.
A look at the output suggests one issue is just a formatting issue, easy enough to fix. Another seems to be failing because it is testing that ABS-only devices are excluded, which is what I'm intending to change here. If I can find that test I'll see about changing it. The last one... I'm not sure what that is about.

I think this line (device_type != DeviceType.GAMEPAD) is obsolete with your change. All gamepads have certain ev_key and ev_abs events, therefore, testing for abs_capa and key_capa is probably sufficient.

For the linter, you can get it to be formatted correctly quickly by doing

sudo apt install black
black input-remapper/inputremapper

(see https://github.com/psf/black)

There is luckily no need to do it by hand

From my side the change looks good!

[sezanzeb]

I'll give it a try maybe tomorrow or something (just a quick test if gamepads still work and such, I don't have a foot pedal), and then merge it if there is no further objection. And I need to run the integration tests locally.

Thank you!
