Ability to audit functions instead of the entire module

[ChrisMayfield]

Modify the audit functions to take either a filename, or a module, or a function. For example, assert_no_for_loops() can be called on a module or function object instead of a filename.

[ChrisMayfield]

Consider making a similar change to other functions that take a filename, for example:

name_date(analysis)
ruff_check(analysis)  # filename or module

As opposed to:

name_date(analysis)
ruff_check("analysis.py")

See check_recursive() and check_while() in tests for PA3 Part C.
