Add script for sorting the seed.txt file

[cthoyt]

if you run python scripts/sort.py it will sort the seed.txt file. This could also be accomplished with bash too if desired.

I could go one step further with this PR to add a GitHub actions check that seed.txt is sorted if you want

Thanks for that. I think eventually a github action is the right way to keep this updated. If GHA would just be a tiny bit more liberal on memory, I could automate the whole repo.
