Commit Message

Luke Jones Aug. 15, 2023, 1:42 a.m. UTC 
  After the addition of the mid fan custom curve functionality various
incorrect behaviour was uncovered. This commit fixes these areas.

- Ensure mid fan attributes actually use the correct fan ID
- Correction to a bit mask for selecting the correct fan data
- Refactor the curve show/store functions to be cleaner and and
  match each others layout
