Add conditional naming of init stub function for building on Windows for Python 3

From @mbaski.

I need to test that this will still build and run properly within Python 2.7 on Windows. I'm hoping Jean can do the same for Linux (I'm not setup to easily build and test on Linux).

Not sure which platforms we care about for this for now, but I didn't see any build or test problems on Linux PY3 64, PY2 64, or PY2 32 bit.

PY3 64

This update worked successfully within Python 2.7 on Windows (I installed the package into python_Windows_64bit_testing and then used MCC to view data from all the thermal models) so I'm good with it now.

Merging and tagging, but note that this is not approved for installation to Ska2 flight with LR approval. This can come along for the ride if any other xija updates drive such a review. It's fine for Ska3 flight / matlab. I guess @jeanconn should check Ska3 matlab32 for completeness.
