FW3X: multiple upgrades...

- upgraded to DSM: lower lows, *much* smoother ramp
- made lows more efficient with underclocking
- fixed party strobe being too blurry
- calibrated UI speed / bogomips multiplier
- added readme to document this hardware's multiple quirks

+# Lumintop FW3X Lume1
+
+A BLF FW3A with a new driver from LoneOceans.  The new driver adds efficient
+constant-current power regulation, RGB aux LEDs, and an upgraded temperature
+sensor.
+
+## Notes of interest
+
+**Flashing firmware**:  The MOSI and MISO pin are swapped, compared to a Hanklight.
+LoneOceans sent a fixed driver design to Lumintop, but the new design didn't
+get produced.  So to flash firmware, swap the wires for those two pins first.
+
+**RGB mixup**: Lumintop seems to have swapped the wires for aux R and aux B.
+This was fixed in firmware in 2023-12, but some lights were fixed in hardware
+before that, so the firmware fix might cause the colors to be swapped again.
+
+**Turbo**: The driver uses regulation for levels 1 to 149, and level 150 is a
+direct-drive FET.  This is by design, and the FET cannot be ramped smoothly up
+and down.  Turbo is a single level at the top of the ramp, with a big sudden
+drop to the next level.
+
+**Moon**: This light has a pretty bright preflash at moon level, and the
+output is unstable so there is very visible ripple.  The user can either raise
+the ramp floor to a level high enough to avoid these issues, or learn to live
+with the ripple and preflash.
