Add a parser for GRGM1200B-like gravity models
Hi all,
As discussed here, the format for some of the lunar gravity models derived from GRAIL as provided by NASA's Planetary Geology, Geophysics and Geochemistry laboratory are not correctly read as they are not in the list of supported formats. I identified this originally for GRGM1200B, but the same occurs for other gravity models provided in the same format, such as GRGM1200L. I am happy to contribute a parser for this format.
