No CFAC/etc. information in projection variable in Regional Radiance files
When converting the Target files (R30x), the Projection infromation does not contain the CFAC/LFAC/COFF/LOFF information. This should be in there to be consistent with the FLDK files
Example uses /delta/ait/dc/jma/himawari08/ahi/2015/2015_05_13_133/0300/HS_H08_20150513_0300_B*_R301*
