The brother_ql.backends package provides backends for
* network (via raw TCP/IP sockets)
* linux_kernel (via device handles like /dev/usb/lp0 etc.)
* pyusb (via PyUSB)
The new backends are in use by the additional scripts
* brother_ql_debug
* brother_ql_print
The code used in BrotherQLReader.analyse() is now is now split into
a chunker() function which separates (=chunks) a data stream of bytes
into individual printer instructions and into the main functionality
of the analyse() method: Stating debug information about each instruction
and generating images of the expected printer output.
