Custom Codecs

Any module that provides encode!/2 can be used as a custom codec:

encode!(value, options)

• value will be provided as a Map containing the generated schema.
• options will be a keyword list with a :pretty boolean, indicating whether the user requested pretty-printing.

The function should return a string to be written to the output file.
