Version 2.01beta1

Bug fixes:
- When using a mixing extruder, the feed rate for extruder-only moves was incorrect
- If additional axes were not created in the order UVWABC then incorrect homing files might be run (thanks chrishamm)
- On the Duet Maestro, the 7th stepper step/dir pin numbers were swapped
- If you paused a print during a G2/G3 arc move, on resuming it the arc centre was at the wrong place. This release defers the pause until the arc move is completed.
- If a command that interrogated the network (e.g. M122 on the Duet WiFi) was sent from USB, PanelDue or another non-network channel, the network subsystem could be accessed by multiple tasks concurrently, causing network disconnections or other errors
- When using a bltouch, between probe points the pin retracted, deployed and retracted again
- M206 with no parameters didn't report the current axis offsets
- During heating, the firmware returned M408 S0 responses to the PanelDue port even if the last request was M408 S2
- Fixed VBUS detection (thanks chrishamm)
- If the resume threshold in the M911 command was set higher than the supply voltage then the save-on-power-off mechanism never got primed. It will now prime at thwe auto-save threshold plus 0.5V or the resume threshold, whichever is lower.
- Fixed "2dtstc2diva=u" in debug printout
- Where a G- or M-code command parameter was supposed to accept unsigned values only, if a negative value was supplied then it was accepted and converted to a large unsigned value

New features and changed behaviour:
- If the firmware gets stuck in a spin loop, the RTOS builds now discard LR and 16 stack dwords in order to get more useful information from the stack trace
- Increased M999 delay to 1 second
- The report generated by M122 now includes a list of mutexes and their owners
- Added SW_ENC pin on CONN_SD to available GPIO ports (thanks chrishamm)
