FourdgsFileReadable class
A file, read by byte range.
Opens the file once and issues positioned reads against the open handle, which is what makes an indexed decode cost the ranges it asks for rather than the file: reading an instant out of a 500 MiB scene reads the index and then that instant, and never anything in between.
