feat: Switch to pure-Rust versions of bzip and zstd in order to pass static compiles

[Pr0methean]

This replaces zip-rs/zip-old#429.

@lolpro11 I've had to partially revert this PR. bzip2-rs isn't a replacement for bzip2 because the latter can compress and decompress and the former can only decompress. Even if that weren't the case, you would've needed to update the usages in read.rs and write.rs.

I understand. Thank you for telling me. The original reason for this PR is because it did not compile statically. Later I found out that bzip only needs the system library during compile time, allowing for proper static compiles.
Therefore, this PR only needed to change zstd (LZMA)
