David Crocker 92c17dede2 Various changes relating to zprobe and non-volatile data
1. Z-probing is now done in two stages: a fast stage at the configured
home feed rate until within 10% of the target value, then a slow stage
at 20% of that feed rate.
2. Provisional support for ultrasonic Z-probe.
3. Added calibration temperature and height temperature coefficient to Z
probe parameters.
4. Z-probe parameters and Z-probe type are now saved to flash memory so
that they survive power-off and reset cycles. Separate parameters are
retained for IR and ultrasonic probes in case both are fitted.
5. Fixed issue with doing slow Z-moves immediately after Z-homing or
probing.

/*
DueFlashStorage saves non-volatile data for Arduino Due.
The library is made to be similar to EEPROM library
Uses flash block 1 per default.
Note: uploading new software will erase all flash so data written to flash
using this library will not survive a new software upload.
Inspiration from Pansenti at https://github.com/Pansenti/DueFlash
