Add the Pimoroni Servo 2040 board (#450) * Add the Pimoroni Servo 2040 board This PR adds the board support package and two simple examples. * Animates a rainbow wheel across the RGB LEDs on the board. * Moves a servo that's connected to GPIO0 back and forth. * Format pimoroni-servo2040 board files * Use us_to_duty function in servo example, clean up comments. * Fix bad types * Add Servo2040 description to top-level readme

Fix servo example in rp2040-servo, remove unusable aliases. The servo example included phase correction, which does not work with the provided divider. Updated comments to explain numbers and also explain alternate calculation with phase correction enabled. Remove unusable aliases from all servo pins. The board includes a 180 Ohm resistor on all servo data pins, which makes the lines not very usable for Spi, Uart or I2C. The aliases were removed given they will rarely, if ever, be used with this board.
