Add ability to populate a Matrix from RAW files with Dredgepack licence

Currently if a user only has a dredgepack licence there is no way for them to use the RAW files to populate a matrix. This can only be done by bringing the raw files into SBMAX, exporting an XYZ and then filling the matrix. Not being able to at least fill a matrix from the recorded dredge depths is annoying and there should be a way to do this, for a number of reasons, with only a dredgepack licence.
