Smart compile functions using JTDDataType

[Ethan-Arrowood]

What version of Ajv you are you using?
v8

What problem do you want to solve?
I want the compileParser function to be smarter (including compileSerializer too)

What do you think is the correct solution to problem?

Adding the following overload to the function:

compileParser<R = unknown, T = JTDDataType<R>>(schema: R): JTDParser<T>;

Will you be able to implement it?
Maybe, I leave for vacation July 22nd-Aug 15th. I may be able to get a PR done today/tomorrow, but won't be available until after Aug 15th to complete it.
