fooof v1.0.0 is available on conda-forge, but it hasn't been updated to v1.1

I'm not totally sure how the conda-forge feedstocks work, but I think it basically comes down to merging this PR:
conda-forge/fooof-feedstock#1

@ryanhammonds - do you know how this works, and know what to do to check / fix if necessary that PR, and do you have permissions to merge it if / when it's ready?
