GitLab

Colab is easily broken by openmm and other software messing with locale.
This mitigation patch lets the %shell and ! work again.
It is much stronger solution than just avoiding shell when making zip.

* Python 3.8 is now what we get in Colab, use it in our Conda as well
* Fix imports, make some unconditional - chain of depencencies makes them
  needed even for relax_prediction==False
* Mitigate spurious error "A UTF-8 locale is required. Got ANSI_X3.4-1968"
  which makes all shell commands defunct - use shutil.make_archive()

Add a .gitignore file

Fix `--cpus_per_task` argument in README

Load pretrained jax weights

Obsolete parsing and File not found fix

Fix for CPU only install

Add long_sequence_inference option to command line

Small fix for prep_mmseqs_dbs.

Because download_mm_seqs_dbs.sh downloads and gunzips its target file (uniref30_2103.tar.gz), this script mistakenly does not process the .tar file. This fix expands the glob to match *.tar*.
