Bugfix
...
The bug was that bitIdx was not being taken into account when we realized that there was enough pixel depth to stay within the current byte when reading pixel values.

If we want a color channel with zero depth then it should default to full intensity, but we will remember that there is zero depth there.

Add PVRTC Pixel class
...
This class accepts a pixels with up to 8-bit components. With the way PVRTC is laid out, there are many different bit modes that we could run into. This lets us change between any that we'd like to deal with.
