Merge rust-bitcoin/rust-bitcoin#2018: Introduce a basic justfile

eccd3fe57b Introduce a basic justfile (Tobin C. Harding)

Pull request description:

  Introduce usage of `just` by adding a basic `justfile`.

  If this goes in we can add various script invocations to it plus other useful things that often get red CI runs (eg, checking no-std).
