v1.0 - *breaking changes* new boards, new features

This release changes the default pins for RP2040 boards.
If you are using a RP2040 in a finished build, do not reset the pin config to the new defaults!

BREAKING CHANGES:

• RP2040 boards use a new default pin configuration, see docs for details.
  Existing boards will not be automatically updated, preserving backwards compatibility.

New Features:

• PID for automatic fan control: automatic mode no longer turns on full blast when you make tea in an adjacent room
• fan kick-start options, see fan_kick_start_* and fan_power_minimum in docs for details
• NEVERMORE_TEMPERATURE_WAIT: useful for waiting for a given chamber temperature
• print_mode_min_bed_target: set a min bed temperature for inferring print-mode
• board support for Pico (non-W)
• board support for Fystec's custom board (part of the Venture XL)
• sensors_voc_expected_variance_independent low level option, see docs

New Features - Experimental:

• ZMOD4410 support
• pins and kipper commands for photo-catalytic and cooler control

Changes:

• update-ota will no longer ask if you wish to reset the pin config; use ./pin-config.py instead.

Fixes:

• servo config not resetting when requesting hardware reset
• SPI bus could be incorrectly inferred from pin
