Create generic method to generate a pydantic class for each function in a module:

[mengerj]

Input: any python module
Output: A list of pydantic classes of all functions (that don't start with "_") available in the module

[mengerj]

Previously no defaults were included in the generated pydantic classes.
The last pull request #241 includes the defaults and the types of the parameters. But since including the types properly needs for all the classes to be available in the environment, it was decided to just use the type Any for all parameter types. But the original class is at least included in the description of the parameter.

[mengerj]

Should allow the method to also work if a single function is provided as input
