#1375 Units for false_easting and false_northing (fix)

[adriaanse-deltares]

Description of Changes

See the description of the issue #1375

I have worked with GIS systems and Geographic projections at Deltares since 1998 and I am 100% sure that:
No exceptions exist where false easting/northing units differ from the projected coordinates. These values are intrinsic to the coordinate system's design and always share the same units

So I propose to remove the scaling of these parameters completely, also for other projections where it is applied.

I appreciate you taking the time to make this PR, and it certainly gave me some hints when trying to untangle what was happening. As I said over in #1375, we probably need to support the scaling in the read path. However, I was able to get the scaling addressed in the write path when writing from a Coverage, which will fix the issue of the NetCDF Subset Service producing netCDF files with mismatched cartesian coordinate units and false_easting/false_northing values.
