Implemented CSWV by adding to old SWV module. Changed storage of forward/reverse current to new data_extra class object to use existing CV plotting code. Renamed Converted Data tab to Extra data. Saving of extra data not yet implemented.

Conflicts:

Pulled data handling into separate method. Added classes for lsv, cv, and swv. (not all complete, but should be basically functional)

Changed dstat_comm to support new communications protocol. Added descended delayedSerial class to send characters individually over serial with 1 ms delay.
