Version 6 library changes
Copyright (c) 2019 Gazoodle. All rights reserved.
1. _BASED moved to template to remove type conversion to long and
sign changes which break int8_t and int16_t negative numbers.
The print implementation still upscales to long for it's internal
print routine.
2. _PAD added to allow padding & filling of characters to the stream
3. _WIDTH & _WIDTHZ added to allow width printing with space padding
and zero padding for numerics
4. Simple _FMT mechanism ala printf, but without the typeunsafetyness
and no internal buffers for replaceable stream printing
