bitmasks from definition files not functional

[tarpas]

Thanks for the tool!

I'm bumping into an error for register definition file

control_word_1 h@0/>H:CONTROL_WORD_1
# Bitmasks
|CONTROL_WORD_1
    0=Reset
    1=Device_reset
    3=Factory_settings
    4=Device_selftesting
    5=Fault_memory_acknowledgement_indicator_relay_K1_and_K2
    7=Advanced_test
    8=Measuring_function_stopped

I always get

    sys.exit(main())
             ^^^^^^

At one point I thought I tried the pipe, but it didn't work. I probably had other eror:

However, the documentation is apparently wrong leading to my struggle here.
#20 fixes it.
