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.

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.

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.

Convert all users of the printer_state("connect") handler to register
a "klippy:connect" event handler instead.

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.

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.

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.

A default of 4 degrees and 10 seconds may be too aggressive - change
the default to 10 degrees and 15 seconds.

Add runtime checks to heaters and temperature sensors to check for
possible hardware faults.
