Create a conda package

[papanikos]

I would really like sesh to be installable through conda.

• conda uses so-called "channels" for distributing packages and the most comprehensive and generally used is conda-forge.

• The process of adding conda packages to conda-forge is documented here.

• Since we are in Go land, here is lazygit's recipe for reference.

I'd be happy to help out with the process, if you would like that.

I'm going to see if GoReleaser might want to add support for Conda, otherwise I can put together something myself, thanks!
