API CHANGE: dut->getDACs and dut->getTbmRegs now properly return the DAC names
instead of their register addresses - since we want to shiled them completely from
the User code!
DAC and TBM parameters: fetching Register Names directly from API now without
having to grep the dictionary.
FIXME: currently the config files are written in the format "0 Name Value" since
I didn't want to change the file parsing. Probably there is a smarter way to do
that.
