typefix netscriptFunctions (see desc)

* Types for InternalFunction and ExternalFunction have been modified to actually typecheck ns functions against docs.
* Internal functions are required to use unknown for any params on the inner function.
* Return types for internal function inner-function must match the respective external function.
* Added new typecheck assertion function for asserting dynamic object types, to allow unknownifying params that were previously hardcoded objec structures.
* Because type assertion for parameter types and return types is enforced by InternalAPI, removed all duplicate type declarations on NetscriptFunction params and returns.
