Title: Adding support for individual segment control

This is what I've come up with to support [individual segment control](https://github.com/sparkfun/Serial7SegmentDisplay/wiki/Special-Commands#wiki-individual) on the S7S. A method similar to what the firmware had been doing before the SevSeg library.

If the msb of a characterToDisplay is set, it goes into bit-per-segment display mode. Each of the lower 7 bits correspond to a segment on the digit.

As the characterArray[] segment map in SevSeg.h is only defined up to a value of 127 anyway, this should only add to the DisplayString method's functionality.
