Trying to package Blockstream’s esplora into Nix’s package manager.

Made me figure out that this app doesn’t have a version number. This is despite the fact that the app it’s a fork of has one. Not a good thing for Nix, as it requires immutability. Will have to resort to a commit hash, I guess.

Still wondering which version number Nix will end up displaying to its users… how will they know how up to date they are? Not convinced a hash would do it.
