Pucrunch (well documented) or eximozer 3.0.2 (better compression)

All these decompressors read the bitstream bit-by-bit and therefore need to perform a lot of shifts which can be challenging on the Gigatron. They also need a working memory buffer of at least 256 bytes, meaning that one of the few low pages has to be reserved for this purpose. One has to be a bit inventive to work around these limitations...
