Methods to apply color channels

[Ignotus-mago]

Much like applyAlpha() method, applyRed, applyGreen, applyBlue, applyHue, applyBrightness, applySaturation. Then call these methods from pullPixelAudio and pushAudioPixel methods. I don't think there will be much of a reduction in speed, and we'll gain clarity by having one method instead of bitwise ops scattered through code. Probably can lose a var assignment or two by calling the methods.

I wrote eight "apply" methods: applyBrightness, applyHue, applySaturation, applyRed, applyGreeen, applyBlue, applyAlpha, applyAll. Each method accepts a float value and an int, which should be an audio value and an RGB value. The float is applied in the selected channel and returned as an RGB value.

The code that call the apply methods was simplified, as expected. This may be all we need to do.

We have applyChannel(float, int) merhods that have simplified calls.
Perhaps further thought is needed for situations where both arguments are RGB int values.
