If channel sampling is not 0, should this size not be divided then?

Implemented, but needs a test file

Does channel sampling affect the expected byte size of a block? Or are there fewer tiles for subsampled channels??

Postponed for now. This feature has been added to the todo list and an error is thrown if any sample rate other than 1 is encountered. Can be implemented on demand, a sample file is required to test it
