Subject: [PATCH 1/2] Fix inverted ChatMix level for SteelSeries Arctis 7/Pro
 (#475)

The chatmix level calculation had game and chat directions swapped:
max game volume produced level > 64 (indicating chat), and vice versa.

This bug originated in the old C implementation (steelseries_arctis_7.c)
and was carried over verbatim during the C++ rewrite (#443). It went
unnoticed because the old code returned a plain int with no defined
semantics for direction, users just saw a changing number. The bug
became observable once ChatmixResult defined < 64 as game and > 64 as
chat.

Subject: [PATCH 2/2] Fix inverted ChatMix percentage mapping for SteelSeries
 Arctis 7/Pro (#475)

The map() output range was backwards: neutral position (255) mapped to
0% instead of 100%. Swap range so percentages correctly reflect volume.
