v1.0.0-alpha: Merge Balance modes, add new funcs, remove FixBrightness

The different Balance modes are separate functions now:

• SinglePlane
• MultiPlane
• SinglePlaneLimited (edgefixer-style limiting)
• SinglePlaneWeighted (bilateral-style weighting)
• SinglePlaneDebug (store results in frame props)

As a result, FixBrightness and Balance functions were removed.

v0.1.1

Bug fixes.

v0.1.0

Just a basic automated FixBrightness function.
