Add decompression tests for zx7/zx0 #768
Description
would be good to add tests for decompressing the minimum supported file size with zx0/zx7
TODO:
- create tests for decompressing 1, 2, and 3 byte files (possibly 0 byte files if zx0/zx7 supports that)
- create tests for decompressing a file that is all zeros
- ensure that zx0/zx7 does not write data outside of the destination buffer (if it is supposed to decompress 10 bytes, then it shouldn't write 11 bytes and etc)
