--program-dir can only be specified before a subcommand

[phated]

Aim

We have a hidden flag called --program-dir that can be specified to set the root of any nargo subcommand; however, it currently needs to be placed before any nargo subcommand, such as nargo --program-dir /foo/bar/baz test.

We should instead be able to place this anywhere, including after the subcommand, such as nargo test --program-dir /foo/bar/baz

Expected Behavior

The --program-dir should be allowed anywhere.

This can be fixed by making it a global flag via the clap macro.

Bug

It is not allowed anywhere.
