+ split AllocateInternalBuffers() into two 32b/8b variants instead of
trying to do everything in one function.

Considering the fact that insert to/lookup from the color cache is always 32
bit, use DecodeImageData() variant in that case.

Tuned the cross_color transform parameter (step) for lower quality
levels. This change gives speedup of 20% at lower qualities (25) and 10% at
moderate quality level (50) with a loss of 0.25% in compression density.
Also removed TODO for cross_color transform. Observed good correlation of
this with the predict transform.

The auto-infer logic of detecting the 'Alpha' use case
(via check '(palette[i] & 0x00ff00ffu) != 0' is failing
for this corner case image with all black pixels (rgb = 0)
and different Alpha values.
-> switch generic use-LUT detection

Added 1 pixel cache for palette colors for faster lookup.
This will speedup images that require ApplyPalette by 6.5% for lossless
compression.

would end up accounting for more than ALIGN_CST and exceed the allocation.

Earlier such images were using roughly 9 * width * height bytes for
decoding. Now, they take 6 * width * height memory.
