Kevin O'Connor 17123889f6 heaters: Make heater.py an "extras" module
The heater logic is an independent module that does not need to be
treated as part of the "core" klipper code.

Kevin O'Connor 8f37700d23 verify_heater: If the heating_gain check fails, just use max_error check
Don't immediately raise an error if the heating_gain check fails.
Instead, just transition to the normal max_error check.  This should
make the code less likely to raise an error should the heater have a
slow approach to the target temperature.

Kevin O'Connor f2ca7d5c66 verify_heater: Improve handling of new targets when temperature is dropping
Allow the first check_gain_time interval to only require a
heating_gain relative to the lowest observed temperature during that
interval.  This makes the code less likely to raise a spurious error
when the heater is enabled while the heater temperature is dropping.

Kevin O'Connor 893bb32d01 verify_heater: Only reset the error count if within the hysteresis range
Don't reset the error counter if the reported temperature is
significantly above the target temperature.  This may help catch cases
where the temperature sensor reports random values.

Kevin O'Connor 864918b1f9 verify_heater: Don't report a heater error if printer is shutdown
Don't log a heater verification error if that error is due to the
printer being shutdown for some other reason.  Those spurious error
reports can be confusing.

Disable the verify_heater checks when debugging, as otherwise it can
cause failures when processing files in batch mode.

Kevin O'Connor aed958eb5c heater: Add PrinterHeaters class that stores all sensors and heaters
Add a PrinterHeaters class that can stores references to available
temperature sensors and stores references to instantiated heaters.

Add a extras/heater_bed.py file and delay instantiation of the
heater_bed object.  This allows the heater.py module to be imported
earlier during the setup phase, and allows the PrinterHeaters class to
be available for registering sensors and heaters.

Kevin O'Connor 849f4ed25f verify_heater: Scale hysteresis duration check
If a heater falls out of the target range, accumulate the temperature
differences to determine if an error should be raised.  This should
make it less likely to report an error for heaters that drift slightly
out of range, and it should make error reporting faster for heaters
that rapidly fall out of range.
