Latest releases not available on conda-forge

[rrjbca]

Are there plans to continue to distribute speclite on conda-forge? The last such release was v0.14 but, as noted in #87, this version is not compatible with the most recent versions of scipy. We have a downstream project that would appreciate if releases continued to be published on conda-forge, particularly the most recent v0.20 release containing the relevant scipy compatibility fix.
