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.

+# Expose bdwidth's motion counter and width reading to gcode macros.
+#
+# bdwidth.py replaces its own get_status() with the runout helper's, so
+# macros only see filament_detected/enabled. This read-only wrapper looks
+# up the existing [bdwidth <name>] object and reports the values it
+# already keeps. It never talks to the sensor, so bdwidth.py stays
+# untouched and updates to bdwidth do not overwrite this file.
+#
+# Install: copy to ~/klipper/klippy/extras/bdwidth_status.py
+#
+# Config:
+#   [bdwidth_status]
+#   sensor: fila_width_0   # name after "bdwidth" in [bdwidth fila_width_0]
+#
+# Status (printer.bdwidth_status):
+#   total_move     - motion counter since Klipper start (raw counts, signed)
+#   last_motion    - counts seen in the last sample
+#   diameter       - last width reading in mm (0.0 on a bad reading)
+#   name           - the sensor name, for SET_BDWIDTH NAME=...
+#   reading        - True while bdwidth is polling the sensor (after
+#                    SET_BDWIDTH ... ENABLE..., until DISABLE)
+#   enabled        - runout response on (SET_FILAMENT_SENSOR ENABLE=1/0);
+#                    says nothing about whether bdwidth is reading
+#   active         - "motion", "width", "all" or "disable" (SET_BDWIDTH). After
+#                    a Klipper restart it shows the config value, but bdwidth
+#                    only starts reading on the first SET_BDWIDTH ... ENABLE
+#   linear_motion  - counts per mm (motion_linear_coefficient)
+#   sample_time    - seconds between sensor reads
