Feature Request: Port/Add Description

[migbro]

Hi! I've been creating a reference of my own, and I noticed that the INFO Description from the source VCF is not carried over when I use an alias in the config (I haven't tried no alias). Would it be possible to use the original corresponding ##INFO header entry (aside from alias for ID) or to be able to specify in config (so like e.description)? I believe it can happen here: https://github.com/brentp/echtvar/blob/main/src/lib/echtvar.rs#L176-L194. I think it'd' also be good to keep/specify Number so as to comply with proper VCF specs. Thanks in advance!

I like this idea!
Definitely open to a PR that implements this. It will have to modify the encoder command and extract the description there and save it to the archive.
I'll try to get around to implementing this, but it's not high on my priority list due to time limitations.

This was solved by PR #34 and PR #35, as of this comment, incorporated into main, but not release yet. Thanks for the help and review!
