[Bug]: missing latitude.py functions

[julesvanirsel]

What happened?

Hey, I tried using the geocentric2geodetic and geoc2geod functions but they weren't available. I was able to use them after adding them to from .latitude import (...) and __all__ = [..] in the __init__.py. There might be a reason they're hidden for some reason I'm unaware of?

With those changes I was able to replicate matlab's geoc2geod results to within an arcsecond:
geoc2geod(0:4:88,6500e3) vs pm.geoc2geod(np.linspace(0,88,23),6500e3)

Relevant log output
