Instead of supporting a single linear range for the temperature
lookup, allow multiple ranges to be defined. This makes the lookup
more accurate when a full lookup table is available.
Update the AD595 sensor to use the full table defined in its spec.

If the c3 coefficient is negative it can cause the adc calculations to
fail. The c3 shouldn't be negative in practice, so fallback to a
simple beta calculation in that case.

Move the Thermistor code to a new thermistor.py module. Move the
Linear code to a new adc_temperature.py module. This simplifies the
heater.py code.

The Thermistor (and Linear) class should handle all the details of
reading the ADC values and converting them to temperatures. So, move
that logic out of the Heater() class.

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.

Most callers did a lookup of the pins module via
printer.lookup_object("pins"). Use that as the standard method and
remove these less frequently used methods.

The existing junction algorithm limits the speed between two moves by
determining the maximum speed an arc between those two moves would
have if the cetripetal acceleration of that arc did not exceed the
printer's maximum acceleration.
However, should the slicer send an actual arc to the printer, then the
existing junction algorithm would not impose any significant limit on
the travel speed of that arc. This would permit the head to travel in
a circle at high velocity and with a greater centripetal acceleration
than the printer's maximum acceleration. To avoid this, impose a
limit on the junction velocity of short moves so that an approximate
centripetal acceleration of that move does not exceed the move's
acceleration limit.

Apply the bed tilt settings immediately after finding them. This
makes it easier for users to perform automatic tilt calibration at the

Drop support for M303 and PID_TUNE, and replace it with a new
PID_CALIBRATE command. Move the logic for this command from heater.py
to a new pid_calibrate.py file in the extras/ directory.

Move the probe_z_offset parameter from delta_calibrate and
bed_tilt_calibrate to a z_offset parameter within the probe config
section. It's easier to understand the z offset setting when it is in
the probe config section.

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.
