[PATCH 1/1] libipa: Allow disabling algorithms via the tuning file

[Isaac Scott]

Allows the user to add "disabled" as a parameter in their tuning file,
which lets them test disabling algorithms without having to delete them.

Usage example:

version: 1
algorithms:
  - Agc:
      disabled:
      AeMeteringMode:
        MeteringCentreWeighted: [ 0, 0, 0, 0, 0, 0, 6, 8, 6, 0, 0, 8, 16, 8, 0, 0, 6, 8, 6, 0, 0, 0, 0, 0, 0 ]
        MeteringSpot: [ 0, 0, 0, 0, 0, 0, 2, 4, 2, 0, 0, 4, 16, 4, 0, 0, 2, 4, 2, 0, 0, 0, 0, 0, 0 ]
        MeteringMatrix: [ 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1 ]
      AeExposureMode:

This example will disable the Agc algorithm.
