Script to fetch unique conda environments

[ewels]

Script to go over all conda environment.yml files and pull out a unique, normalised set (consistent whitespace, no comments).

Will be useful when requesting initial set of Seqera Containers for all modules.

669 * 4 = 2,676 Wave builds we need to request 😅 (Docker, Singularity, arch, arm).

Not really intending to merge this in as we hopefully won't need it long term, just putting it here for reference / so I can find it again.

I started putting together a script to do a first pull + bulk update of all modules. It deliberately runs slowly, waiting for container builds, so as not to hit rate limits.

I started running but remembered that when we introduce Conda lock files we will need new builds for all of these, no point in doing it yet.

Needs a little more work to extend to singularity / arm but should be about ready once that's done.
