ika a8fcd8d07e 0022820: OCCT IGES writer loses plane information
added writing planes in Type 108 not like BSplines
pcurves for planes not writing
add parameter for choice between writing planes in BSplines and Planes
0022820: OCCT IGES writer loses plane information

pcurves were prohibited also for BRep mode
Adding test case for this fix
