Phil Howard 2cc6514583 Slow set/clr_bit writes a little
We chased a bug with handling/clearing interrupts on Encoder into the depths of madness, finding that a Debug build would magically fix the bug.

Turns out it was probably just us being a little aggressive with the poor little MS51-based Encoder driver.

* Fix delays to be more delayey.
* Replace big 'ol loop and boolean with straight up checks and an early exit- the bit-addressed regs are never going to change

Phil Howard 815e784625 Plasma 2040 library & examples
Library:

Includes classes for driving WS2812 and APA102 LEDs and defines for Plasma features.

Encoder Example:

Supports connecting a Rotary Encoder via the Qw'St connector.

Works with APA102 or WS281X pixels.

Pressing A will cycle between:
1. Colour change
2. Brightness change
3. Cycle delay

Pressing B will switch back into auto-cycle mode.

Turning the encoder at any time will switch out of auto cycle mode into parameter adjust mode.

Also includes a bugfix to Rotary Encoder for getting the interrupt correctly.

Rainbow Example:

Basic rainbow cycle, press B to speed up and A to slow down.

Phil Howard 77839e2a6a Tidy up constructors, drop unused variables, const single addr
Removes i2c_inst_t from constructors since it's ignored, and updated the Python bindings not to supply this argument. Instance is inferred from the supplied pins.

Phil Howard 445737088f Switch drivers over to I2C class, tidy up common include
Removes all driver-specific SDA/SCL pin definitions and defaults.
Pin type is "uint" everywhere, but "PIN_UNUSED" is *int*_max for MicroPython compat. That's still a lot of pins!
Adds baudrate to the I2C class, and allows a driver (like Trackball) to check the baudrate is supported

Phil Howard 42c7555c96 Add common I2C class
This change adds a common I2C class, gathering various I2C functions into a single point of responsibility.

It's necessary for correctly managing the I2C bus pins and state across multiple devices.
