Feature request: Support for BUTTON events in Eyelink ASC file parser

[WouterKroot]

Describe the new feature or enhancement

I’m currently using read_raw_eyelink() to load Eyelink ASC files, but I noticed that BUTTON events in the ASC files are not captured or annotated.

I checked the code and it seems BUTTON events aren’t supported yet.

Is there any plan to support BUTTON events? Or is there a recommended workaround to include BUTTON events as annotations?

Thanks a lot for the help and the great package!

Describe your proposed implementation

In the create_annotations in mne/io/eyelink/_utils.py add 'BUTTON' to handle:

raw = read_raw_eyelink(path, create_annotations=['blinks', 'messages', 'buttons'])

Describe possible alternatives

manually parse

Additional context

@WouterKroot would you be up for adding support for BUTTON events? And maybe the default create_annotations=True should include these events (would count as an enhancement I think). cc @scott-huberty
