Read .dm3 and .dm4 image files

Read Digital Micrograph files for electron microscopy

You are now following this Submission

Electron microscope images and image stacks are stored in a proprietary fromat by Digital Micrograph (Gatan Inc.). This function reads version 3 and also the new 64-bit version 4 files. This replaces the ReadDM3 function in my previous post #27021, "Imagic, MRC and DM3 file i/o"
