verboseLevel, txPin, rxPin not used?

[olivluca]

I'm trying to update my code to use the new version of this library (just the LinFrameTransfer class) and I cannot find where verboseLevel, txPin and rxPin are actually used.
In fact I did a quick test and changing verboseLevel does nothing (unsurprising since debug output is controlled by constexpr debugLevel debug = debugLevel::verbose; in LinFrameTransfer.cpp).
I didn't check if txPin and rxPin actually work, but I doubt they do.
