Move the g-code command handlers to a new class. This reduces the
size of the main Toolhead() class.

If switching a pin from output low to input with pullup, there is an
intermediate state of either driven high or high impedance without a
pullup. Similarly, when switching from output high to input without a
pullup, there is an intermediate state of either driven low or high
impedence with a pullup. In both cases it is preferable for the
latter transition.
Also, calculate the final setting prior to making any changes to
reduce the time in that intermediate state.

Don't leave the wires in a high output state during setup - leave them
in a high-impedance with pullup state.

The get_temp() code will stop reporting the last temperature of the
heater if there hasn't been any recent temperature updates. However,
on a full mcu communication loss this can cause the verify_heater code
to report a heating error prior to the mcu code reporting the
communication failure. Increase the heater timeout from 5 to 7
seconds to make it more likely the mcu failure is reported first.

SHT3x would return a read NACK on host retries.
When the MCU receives the I2C CMD, it reads out data.
SHT3x clears the data buffer.
The MCU fails to deliver a response to the host.
The host retries, the device returns NACK,
then the MCU goes into the shutdown state.
Make sure there is at least 0.5s between retries.

Avoid using the name "config" as a local register storage variable as
it can be confused with the common "config" configfile reference.

Commit d120a313b incorrectly removed an assignment to self.config - in
this instance the reference was to a local variable not related to the
global configfile storage.

The more.musl.cc site is blocking downloads from all github actions,
which makes it difficult to use that site for the ar100 cross build

replacement.

Update Code_Overview.md to note that the config object should not be
stored after the "config loading phase".
Remove a few inadvertent cases where a 'config' object was stored
in module member variables.
