Longitude cross over in LCC projection #288

If we have a coarsegrid with longitude having Dateline crossover +178 and -178, the LCC projection does not handle it properly. I tried to cross check with proj4 LCC implementation. For +178, the x y values are matching with proj 4 but not for -178.

The reason may be that longitude wrap around has been are handled around in 2018 in proj4 in version 5.0 while seeing at the history of the ossim Lcc projection implementation there are no major changes in it after 2015
