subplot 0.4.3

# This is a nix "flake" which is used both by `direnv` and to offer
# a quick way to acquire `subplot` in a nix/nixos environment.
# If you have `direnv` support, just allow this tree and you should
# be able to develop `subplot`.  If you use this as a package flake
# then the `subplot` package derivation is available in the usual way
