[#89] Reuse existing megaparsec parsers

[Kariel-Myrr]

Description

Problem:

We had a lot of repeating code in FromHttpApiData instances with CLI.Parse.

Solution:

That was fixed. Basically a lot of low parsing logic moved from CLI.Parse to CLI.Types and Coffer.Path. It was necessary to avoid cyclic dependencies.
