refactor: rely on clap for parsing in `miden_wrapper.rs`

[lima-limon-inc]

Currently, the miden interface related code handles parsing, it does not rely on auxiliary crates like clap for instance. However, I believe we could/probably should rely on clap for miden as well, since:

1. We're already bundling clap in the binary itself, since midenup uses it.
2. It already handles cases like this.

Using clap would probably reduce the amount of code we have in miden_wrapper and would avoid common pitfalls like the -h vs --help case
