Change the default CANbus frequency from 500000 to 1000000. A higher
frequency allows for greater data transfer rates, lower latency of
messages, and should overall be more robust.

Recommend USB to CAN adapter and no longer recommend using the
waveshare rpi hat.
Recommend using allow-hotplug for all USB adapters.
Note bandwidth limitations when using USB to CAN bridge mode.
Note that a USB to CAN mcu is not a USB serial device.

The control bytes for the AHT20 and AHT21 are identical to the AHT10, but I had not been able to test just yet to ensure the sensor code supported the other sensors. I've wrapped up testing and updated the comments/docs to reflect this additional support.

In some condition ，“drvstrength 2” does not work. According to page 17, some mosfets need “drvstrength” set to 0 .
From datasheet rev1.15, the DRVSTRENGTH reset default is 0 . (instead of 2)

The stalled_bytes counter refers to the number of bytes that are not
yet eligible for transmission. However, the naming leads to confusion
as it could be interpretted as an inability to transmit data. Rename
to upcoming_bytes to try to avoid that confusion.

Add an optional REGISTER parameter to DUMP_TMC so that the output is more filtered/cleaner for manual TMC calibration.

Previously, the globalscaler was calculated during the config parsing and set to a fixed value. If the current was changed for any reason after the initialization, only IRUN and IHOLD would be changed. This however caused issues:
- If the new current was lower, then the resolution of the possible current values would be low since there are only 32 IRUN/IHOLD steps.
- If the new current was higher, it wouldn't actually work since IRUN and IHOLD are capped at 31, so it wouldn't be possible to increase the current without increasing globalscaler.
With this commit, the globalscaler is recalculated whenever necessary in order to ensure the correct range of IRUN/IHOLD is used.

Make all the microstep lookup table registers configurable via the
config file. It also loads the default values.
TMC220x and TMC2660 do not support this feature.
