Functions of `loxodrome` or `rhumb line` is needed

[AkexStar]

I have did a lot of surveys, but found that there is few libs about rhumb_inverse and rhumb_direct. I noticed that Geographiclib has a solution for rhumb, but does not support python. pyproj has geodesic.inv_intermediate and geodesic.fwd_intermediate for great-circle(geodesic), but lacks of functions to calculate rhumb line.

Rhumb Line is very important for air/sea track calculation. I hope that there will be funtions just similar to geodesic.fwd_intermediate to compute rhumb line.

I will be very grateful if any developer could reply me.
