[THREDDS #TND-409701]: Please add LambertConformalConicEllipse (and Albers, AlbersEllipse) to WCS

Hi Rich,

The problem is that we can't currently write valid GeoTIFF files using these 
projections. The netCDF-java library can handle data in these projections. The 
TDS can serve the data over WCS just not if a GeoTIFF response is requested.

Updating the GeoTIFF code will require a bit of coding and some digging into 
the GeoTIFF spec to figure out the appropriate tags. I will toss this over to 
our GeoTIFF person, Yuan, to see what he thinks.
