bml_neuroomega_info_depth

 BML_NEUROOMEGA_INFO_DEPTH returns a table with .mat file information
 aggregated by depth. Useful to select relevant depths

 Use as
   info = bml_neuroomega_info_depth(cfg)

 where cfg is a configureation struct with the following fields
 cfg.path - string: path where to look for the .mat files
 cfg.sort - string: variable by which to sort the output table
 cfg.direction - string: either 'descend' (default) or 'ascend'

 Returns a table with variables
   depth - double: position of the record in mm
   files - double: number of files at this depth
   size - double: aggregated size of all files in MB
