Updated options for HTSlib dockerfiles

[johnmcgonigle]

A lot of people still use biocontainers so I thought it would be useful to have some updated versions of existing docker files using the new libs.

I've kept the format essentially the same as the previous versions.

can't modify multiple containers in a same pull request

[johnmcgonigle]

I'm not modifying any containers, I'm adding 3 new ones.

Or is that you can't add 3 containers in a single pull request?

Would you prefer them as 3 separate pull request?

Hi,
We have automatic checks (and previous comment is part of it, though using my id).
Indeed, any container 'new or update' must be in separated pull requests.
If one depends on an other, please just specify it in PR text.

Thanks
