overhaul for the NoritakeVFD driver (idea by Richard Moratti):

- Fixed vbar & hbar - Allowed for displays with 2 custom characters
- Fixed cursor off  - 16H - Data sheet for CU20045SCPB has error -> Cursor Off 14,16,17H
- Tested with CU40026SCPB-T20A - 40x2 - Hardware Defaults to 19200 8E1
- Added new config parameter [Parity] to set serial data parity 0(none),1(odd),2(even)
- Added config parameter OffBrightness
- added support for big numbers
