Initial import of my Klipper macros, modules and scripts

Macros as they run on the printer (Voron 2.4 + AFC Box Turtle +
Blobifier + Beacon + bd_pressure + bdwidth + iHeater), the Klipper
modules they need (xy_drift, bdwidth_status, bdpressure_check), MCU
firmware update scripts, install.sh with Moonraker update manager
support, and READMEs.
