Implement initial support for MKS Robin (STM32F103ZET6) board.
Custom build script is used to generate encrypted firmware compatible with original MSK Robin bootloader (i.e. safe firmware update from SD card and possibility to go back to original close-source firmware).
-Disable LDF "deep+" mode on AT90USB platforms. Appears not needed any longer (likely due to fix 7322df26ad). Results in identical binary output and cuts compile time in half
-Disable Cartesio config from CircleCI (compile failure)
-Disable Geetech I3 Pro X GT2560 from CircleCI (compile failure)
-Enable EEPROM on Micromake example config (fix compile failure)
-Move FolgerTech/i3-2020 to AVR platform in CircleCI (fix CirculeCI build failure)
-Disable various examples failing to build in CircleCI
-Enable various examples no longer failing to build in CircleCI
* Add traceback after watchdog timeout
Add the cpability to perform a traceback following a watchdog timeout.
* Enhanced hardware SPI
Allow use of either SSP0 or SSP1.
Ensure that no data is left in I/O buffers after calls to enable sharing of SSP hardware.
* Make flash emulation of eeprom the default
Make use of flash for eeprom storage the default. This means that usage of eeprom will not cause USB drive mount/unmount operations.
* Allow sharing of SD card
SD card I/O operations from the USB stack take place in idle loop, rather than at interrupt time. Allowing sharing of the SPI bus.
New configuration options to allow usage of the SD card to be specified.
* Fix problem with hardware SPI pins

-Enable boards_dir option in PIO INI
-Remove defunct custom board file operations for PIO auto-build environment
-Remove now-defunct Teensy++ 2.0 PIO entry, replaced by `at90USB1286_DFU` and `at90USB1286_DFU` (using this entry always put AT90USB board boot loaders in jeopardy of being overwritten due to the very small size of the official Teensy++ 2.0 bootloader)
