Closed via #122, and small changes in various other pull requests.

@mmalenic Are we really reusing functionality from noodles-htsget? I cannot see it even being imported on https://github.com/umccr/htsget-rs/blob/main/htsget-search/Cargo.toml :/

IIRC, when looking at the noodles-htsget crate, we concluded that we could nuke a ton of our own htsget-search crate, and it doesn't look like that right now?

Let me know if I'm wrong, if I'm not, reopen please ;)

My bad! For some reason I had completely forgotten about that side of noodles. You're right, some of the structs look like they could be used from noodles-htsget (although it seems like parts of it are private), although most of the 'searching' logic would still need to be ours I think.
