pslua opens the output file via withFile WriteMode (exe/Main.hs) without creating its parent directory. If --lua-output-file dist/X.lua is passed and dist/ does not exist, it aborts with withFile: does not exist (No such file or directory).

Surfaced in purescript-lua-assert, whose scripts/build writes into a gitignored/absent dist/ (worked around there with mkdir -p dist; see #59). Hardening pslua to createDirectoryIfMissing True (takeDirectory out) would remove a sharp edge every fork's build script otherwise has to handle.

Low severity, trivial fix.
