Seem like a problem if we want to pack a float but give a int. |

CPython allows pack float format with int, float or class with float() but not a float like string. Non of our function doing exactly the job. We may need one it also can be use by array.array

I think IntoPyFloat::try_from_object is correct; it accepts float, int, or anything with a __float__ method

I modified it in #2309 to not accept a float string, since that's what PyFloat_AsDouble does

This is sort of a big lump change, and there aren't necessarily tests to prove it, since there aren't any tests in
test_struct.pythat verify the native ordering -- even though there's padding now and correct alignment/size, the tests that I unskipped aren't related to that 😞 . Still, I think this is cleaner then it was before; there's an enum for the codes now, and finding thepack()function for a code is a bit cleaner now and respects endianness/architecture
