Various ossfuzz fixes

Use 1st eccentricity instead of 2nd eccentricity

2019-03-16T09:21:26+00:00

By mistake the second eccentricity was used in a few places in the
Molodensky transform. According to the literature the first eccentricity
should always be used in the eccentricity.

This only affects the output slightly. Reported test coordinates
differed by less than a millimeter.

Fixes #1321

deformation: Replace +t_obs with +dt

2019-02-14T13:55:23+00:00

The +t_obs parameter was confusing for users since it effectively
overwrote the observation time in input coordinates. To make it more clear
what is the operation is doing, users are now required to directly specify
the time span for which they wish to apply a given deformation. The parameter
+dt has been added for that purpose. The new parameter is mutually
exclusive with +t_epoch. +dt is used when deformation
for a set amount of time is needed and +t_epoch is used (in
conjunction with the observation time of the input coordinate) when
deformation from a specific epoch to the observation time is needed.
