release: release all dependencies to conda-forge

[sbillinge]

Problem

All recut diffpy packages need to be released to conda-forge

Proposed solution

have a meeting 6/27 with @sbillinge and @Tieqiong (and @cadenmyers13 if he likes) and bang this out?

@sbillinge sent a request to the diffpy-cmi-release channel on slack to arrange this and sent a tentative calendar invite
