hidpp10: Parse G9 profile

Browse Source 
This allows to read but not write profiles from the G9.

The dpi mode sturct is a little different as the mouse only supports
symetrical dpi for x/y. Given the current naming a suffix of _sym
was the best I could come up with.

The G9 profile has some additional unknown bytes compared to the
others. Unfortunately the content of them varies for the 4 first
profiles and the last. So adding a default value for the like with
the G700 is not possible. For this reason I dropped implementing
the write part for now.

Something else to address is that this mouse only has 10 buttons
compared to the usual 13 that we have in PROFILE_NUM_BUTTONS. For
now I just hardcoded it in the profile and hidpp10_get_profile.
