PR summary

downloads "current" binaries into nix-shell

something like the hcup idea but for nixos

sits on top of #1292 (land that first)

part of the release process will be to bump the version and hashes once artifacts are deployed, this will need to be iterated a few times to make it smooth

at some point (soon) we will want to make it easy for consumers to pin binaries as well as roll forward with each weekly cycle

supports mac and linux (although i don't have a debian/ubuntu to test on)

questions

testing/benchmarking notes

( if any manual testing or benchmarking was/should be done, add notes and/or screenshots here )

holochain and hc should be available in nix-shell

# should error
holochain -V
# should error
hc -V
# drop into nix-shell
nix-shell
# should report holochain 0.0.12-alpha1
holochain -V
# should report hc 0.0.12-alpha1
hc -V
