BROKEN: try to update htslib

I'm lost on trying to keep things building. Do either of you see how to fix this?

Right now, I get:

======================================================================
ERROR: cyvcf2 (unittest.loader._FailedTest)

It seems that the errors are largely due to the compilation of CPU feature specific code in htscodecs submodule. My quick attempt to include all the source code failed :( Feel free to revert my change
