Support for jq modules

[chancez]

Please describe your feature request.

I would like to write reusable jq/yq modules that I can use with yq. Eg: https://jqlang.org/manual/#modules

Describe the solution you'd like
I want to have a modules defined in ~/.jq or ~/.yq, etc, to be automatically available as modules with the option to use -L to provide my own search paths as well.

Describe alternatives you've considered
Import/include functions could be added in addition, or as an alternative to modules, but modules would still be usefl.
