bzip2 symbols like `BZ2_bzWriteOpen` are not present in `libcrystax`
(At least) the following symbols are nowhere to be found in
BZ2_bzWriteOpen BZ2_bzWriteClose BZ2_bzWrite BZ2_bzReadOpen BZ2_bzReadClose BZ2_bzRead BZ2_bzReadGetUnused
Maybe others as well. Am I doing something wrong or are they supposed to be somewhere else?
