If the choice mapping uses integer keys then lookup the config option
using self.getint(). This simplifies the callers and improves the
encoding of the printer.configfile.settings export.

Writes to the max31856 chip use "burst mode", so only one address
during the initialization sequence can be sent. This fixes erroneous
"Cold Junction Fault" errors.

Rename try_load_module() so that it uses consistent naming for
"printer objects". Change the function to raise an error by default
if the specified module does not exist.

The heater logic is an independent module that does not need to be
treated as part of the "core" klipper code.

Commit c3efcd9c moved the config_spi setup to a build_config callback.
It's also necessary to move the config_thermocouple to a build_config
callback as well.

Change the name of the config registration method and pass an explicit
reference to the callback to the new method. This makes the
relationship between mcu registration and build_config() more clear in
the calling code.

Don't pass pin_type to lookup_pin() - instead, if a pin can be
inverted or can have a pullup, then the caller must explicitly specify
that when calling lookup_pin(). This simplifies the code for the
cases where it is not valid to invert or pullup.
Explicitly pass the pin_type to setup_pin() and have ppins.setup_pin()
apply default pullup and invert flags.

Make sure to use is_init=True when sending query_thermocouple -
otherwise, the config CRC is likely to mismatch on every connection.

Raising an error from the background message reception thread isn't
well defined. Instead, on a temperature fault, invoke a printer
shutdown.

Those chips that require an spi init sequence can generate the message
directly in the chip specific class.
Also, don't send an spi init message for chips that are read-only.

The MAX6675 chip has a different read sequence than the MAX31855 chip.
