fix(cmd): Correctly parse module options when passed from command line

[elldritch]

Would love if you could take this over and add a test (it's fine to test as a follow-on if this is time-critical to merge).

This makes a lot more sense to me after I started trying to write the code myself. Looks good to me, will add a test in a follow up PR.
