PIC32: add flash algorithm support
Add flash algorithm support for the PIC32MX.
Still a few things todo but this dramatically decreases
the programing time, eg. approx programming for 2.5k test file.
- without fastload: 60secs
- with fastload: 45secs
- with fastload and algorithm: 2secs.
Add new devices to supported list.
