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.

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.

Another bug fix.
...
In the previous commit, we simply accomodated for alpha errors when compressing single color partitions. In fact, the issue was a bit more greivous: we weren't computing the proper error term at all! This fixed that function so that we emphasize the error metrics induced by *squaring* the error in each channel and then returning that as a measurement of the acceptability of using a single color compression for that partition.

Bug fix
...
When the compressor recognized that a shape was a single color, it determines
an optimal encoding for that color. However, only the error in the single
pixel was returned as the error for the overall shape. This caused problems
with modes that do not support alpha and shapes that do have alpha.
