lampbench station / export / label / tm30 / calibrate replace the Python lamp_station.py, lamp_export.py, label_printer.py, tm30.py and calibration.py that lived in HPCS6500-py. The driver is a submodule (HPCS6500/, like mppt-testbench). Workspace crates: tm30 (TM-30-18 port of colour-science 0.4.7), brother-ql (raster protocol, byte-identical to brother_ql) and lamp-label (QR + ID labels for the QL-820NWB). Bundles are byte-identical to lamp_export.py's (golden tests); the station runs end to end in a test against the simulated instrument.
