Check definitions for eccentricity + longitude of periastron in `exoplanet_core`-based `inject_transit` #212

A student in ASTR3510 just used @catrionamurray 's exoplanet_transit in inject_transit and ran into weird behavior where the transit time changes if the longitude of periastron changes. I think this is a difference in how exoplanet/starry defines reference points and how things like batman define reference points?! I'm not 100% sure this is actually a problem, but I wanted to flag it as a potential thing we should document carefully.
