Mirco Miranda 463da81fad IFF: support for PCHG chunk
Highlights:
- Adds support for a new palette changer chunk. Some test cases attached to #38 .
- Fixes the reading of ILBMs with the mask (test case: [cyclone.iff](/uploads/d8734d2155fd0d21f7b003b37e0d1259/cyclone.iff)).
- Adds support for HAM5 encoding.
- Adds more test cases created using [HAM Converter](http://mrsebe.bplaced.net/blog/wordpress/).
- Adds support for Atari STE RAST chunk outside FORM one (test case: [fish.iff](/uploads/c461cf4b6a1423cec60fbce645d9fd07/fish.iff)).

NOTE: I contacted Sebastiano Vigna, the author of the PCHG chunk specifications, and he provided me with:
- Some images to test the code (but I can't include them in the test cases).
- Permission to use [his code](https://vigna.di.unimi.it/amiga/PCHGLib.zip) without restrictions: Huffman decompression was achieved by converting `FastDecomp.a` via AI.

Closes #38
