Always generate the version through git when possible, and encode that within the binaries so that `catala --version` does'nt give misleading information. Previously we used dune's builtin functionality, but that resorts to a hack at install time which is unpleasant and doesn't work with our use of `opam install`. The cost is a re-linking of catala_utils and the binaries upon git commit, which is hardly noticeable.
