2.5.7 - better fix for #593, and SerialUPDI fixes

A better fix from @MX682X relating to the wire buffers is now added. This fix should be better than what we had in 2.5.6,

SerialUPDI had a bug that had not been noticed which prevented the standalone read operation from working That has been corrected. Also there are two more serialUPDI related changes:
More menu options to help the users whose combination of adapter and OS requires the write delay.
Verbose mode now works - I adjusted the priority of logging messages so -v is reasonable, while -v -v is rhe one with too much information for almost anyone.
