Some file formats contain non-image data, commonly called "meta-data". This command extracts meta-data from an image file.
The image file is specified by imagePath. If imagePath is empty, a file selection dialog is presented.
The metaData are returned in two arrays, metaTypes and metaData. The metaTypes array holds the types of the metaData; 4-character strings, identifying the kind of the metaData. The metaData text array holds the data itself.
