API for compress_multiple is too restrictive on progress argument

Hi!

Currently, the progress argument of compress_multiple is checked with PyFunction_Check.

Most of the time, it is fine. But there are cases where this check fails (e.g. partial, or compiled function with Python compiler like SCons).

I guess that any callable would be good for pyminizip right? So why not checking the progress object with PyCallable_Check which has the same signature than PyFunction_Check

int PyFunction_Check(PyObject *o) Return true if o is a function object (has type PyFunction_Type). The parameter must not be NULL.

int PyCallable_Check(PyObject *o) Determine if the object o is callable. Return 1 if the object is callable and 0 otherwise. This function always succeeds.

Example when passing a compiled function

Type of progress is <class 'compiled_function'>
