Add HS80 Max support

[emericg]

Changes made

Added HS80 Max (0xa97) to the CorsairVoidV2W class. Sidetone confirmed working.
I did not add 0x2a0f ID because another issue mentioned it was a different type of HS80 Max?

The battery level wasn't working, as stated in the previous comment all I got was 271%, the 0x0a96 headset ID, but the battery level always follows in the next packet or so, so a simple retry was enough. Maybe that's made to signal per device battery level, but I only have the one to validate that theory.

I added a wakeDevice() function that doesn't do the full "software mode" switch, because it turns out that was what was producing audible pop sound + subtle volume level change in my headset, made worse by using the HeadsetControl applet for Gnome (a query every couple of minutes).

The pop still happens when changing sidetone or setting the inactive timer, but it's more acceptable because it's triggered following a user action and not happening out of nowhere.

Implemented setting the inactive timer and MICROPHONE_UP support (both taken from OpenLinkHub code).

Cleanup the code style a bit, in a separate commit if you don't want it, I would personally also rename the class to get rid of the "void" in the title.
And thinking about it now, I did not changed the README to add "inactive time" and "rotate to mute" (but I only tested with my HS80 Max).

Checklist

• I adjusted the README (if needed)
• For new features in HeadsetControl: I discussed it beforehand in Issues or Discussions and adhered to the wiki
