Update libdeflate (mirroring issue in hts-sys)

[davidlougheed]

See rust-bio/hts-sys#15 and rust-bio/hts-sys#16

Updates to libdeflate have fixed bugs, added more CPU support, and increased performance (see e.g. https://github.com/ebiggers/libdeflate/blob/master/NEWS.md#version-114 ). Personally, I use rust-htslib in a context where BAM read/decompression speed is a major performance factor, so having the ~20-30% performance increase from at least v1.14 would be quite useful.
