OBJ Importer - Material file .MAT - not import maps declared map_D

[Molder72]

For mesh exported from Daz Studio,
The Opacity Texture is not fill because in the .MAT file exported from DAZ the opacity is declared map_D but 'OBJ Importer' only detect map_d with the lowercase '_d', I suppose.

example from Daz
map_D /ConvertedMaps/Girl8Eyelashes_1001.tif

but map_D is not detect, and the relative texture file path it's not added to the houdini material
then, if I modify the .MAT file like this
map_d /ConvertedMaps/Girl8Eyelashes_1001.tif
the texture file path is detected and added to the houdini material

only tested for Daz mesh
