adding ivar version 1.4.3

[erinyoung]

There's a new version of ivar!

It looks like this is mainly minor changes according to the release notes https://github.com/andersen-lab/ivar/releases/tag/v1.4.3

I, however, have made some major changes from the Dockerfile in 1.4.2:

1. I added a builder stage where samtools, htslib, and ivar are installed
2. There is no longer bedtools, bwa, or minimap2. I have tried using ivar's piping method, but it too slow for my purposes. If someone else uses this option, let me know and I can add them back in
3. I added a CMD line
