[WIP] GitHub Actions for CI

[lonsbio]

Initial attempt at converting Travis CI script to GitHub Actions.

Due to large amount of files, rolled into one stage rather than separate build and test, and separate steps for sub stages. Could be optimised further.

Currently failing at the diff STRs.tsv ../.testing/STRs.benchmark.tsv step , however unclear initially if this is a CI issue, or an actual regression that is being found

  cd $STRetch/test/
  diff STRs.tsv ../.testing/STRs.benchmark.tsv
  head *.locus_counts *.STR_counts *.median_cov
  head *.tsv
  shell: /usr/bin/bash -e {0}
  env:
    pythonLocation: /opt/hostedtoolcache/Python/3.10.0/x64
    LD_LIBRARY_PATH: /opt/hostedtoolcache/Python/3.10.0/x64/lib

Thanks @lonsbio! I'll see if I can figure out why the files are different.
