Fixed

• Missing serialisation for from-unix and from-abstract.

Changed

• Rule files (-f) are now just a list of newline-separated rule (-r)
  arguments instead of YAML files.
• Improve and overhaul README and man page.
• Split build instructions into separate file.
• Include URL to README in usage if manpage is not being built.
• Turn into a Nix Flake.

2.1.3

Fixed

• Pass linker version script to the linker instead of the compiler.
• Compile with -fPIC again (regression from version 2.1.2).
