refactor: simplify default resolvers and local storage data

[mmalenic]

Closes #239, there's no need for the defaults to be any more complicated than a 1-1 mapping.

Changes

• Change default resolvers to .* and $0, and default local storage locations to the current directory.
  • When running with default settings, data can still be fetched from data/.../<id>.
  • Docker examples also work with a 1-1 mapping between the mount point and url paths.

Thanks @mmalenic!

So if I understand the description of changes correctly hartwigmedical/hmftools#541 (and other third parties like GA4GH and NBIS) don't need to change their docker run nor client invocations because data/ is greedily matched now via .* (instead of (data)/(.*)).

Great!

Yep, basically, data is now matched like any other path component. If it's present in the directory htsget is launched from (or mounted in the docker container), it can used as a file source, and so can any other directory.
