imformats: memory lock function to prevent "registry" of imageIO to be cleared * image/imformats.m: imformats has a persistent variable that keeps a list of supported formats with their respective reading and writing functions. Packages are recommended to register new formats via calls to imformats(). To prevent reseting its state each time a user calls "clear all" we must lock it to memory.
