RatOS V2.0.0 Alpha 4

Long overdue, it's finally here, RatOS v2.0. This release contains a ton of new features.

Preliminary docs: https://rat-os.vercel.app/

RatOS v2 is not backwards compatible with RatOS v1, you will have to reflash

this section will be continuously updated

Major new features

• Now based on bullseye
• The RatOS configurator will now help you flash your controlboard and toolboards.
• Toolboards are now supported.
• Stowable probes like euclid and klicky are now support.
• Unified homing: everything is now handled through a single homing override. Sensorless homing now requires no tinkering with homing macros (you still need to tweak current and sensitivities). Including a stowable probe config automatically enables deploying and stowing. Axes can now use individual homing procedures, such as sensorless on X and endstops on Y.
• MainsailOS has been merged which brings timelapse and crowsnest.
• Preinstalled: https://github.com/worksasintended/klipper_linear_movement_analysis
• Klipper now runs Python 3

Minor new features

• A bunch of new macro variables to tweak the RatOS macros (see https://github.com/Rat-OS/RatOS/blob/v2.x/site/docs/configuration/macros.md), including end park z hop, prime positions, etc etc.
• Configurator now maintains klipper and moonraker extension symlinks (will automatically restore in case of a hard reset, can also be triggered automatically through the configurator actions menu at RatOS.local/configure)
• Configurator now in charge of flashing all connected boards when klipper is updated.
• START_PRINT can now use the hotend to measure chamber temp. For example to wait for chamber to reach 40 degrees, use START_PRINT CHAMBER_TEMP=40. The bed temperature during chamber heating is configurable via the macro variable variable_start_print_heat_chamber_bed_temp.

Bug fixes

• IPv6 has been disabled (hopefully no more issues with RatOS.local / moonraker not working on IPv6 capable networks).
