Fixed bc5 decoding
...
BC5 decoding uses only 2 channels instead of 4. The current algorithm did not initialize the RGBA struct which resulted in random values in the output image. This commit should initialize the decoded RGBA struct, thus setting B and A values to default (0).

Found edge cases with custom qtables
...
And there was a lingering bug since the previous qtable unsigned char fix
(#1814 ) since the call to array.array was in another place, the roundtrip was no
longer equivalent.
That was a minor change, but the revised test wouldn't pass because saving an image
with one custom qtable automatically adds a second to it by the call to
jpeg_set_defaults.
With 1 or >2 custom tables, there is extra work we have to do due to that call.
