Disallow imports from fp-ts modules (fp-ts/no-module-imports)

Disallow imports from fp-ts modules, such as fp-ts/Option.

The function module is an exception and it's allowed nonetheless, since it's not exported from fp-ts's index.

🔧 Fixable: This rule is automatically fixable using the --fix flag on the command line.
