Hi, Hope I haven't caused chaos trying to create this PR.
I've written a DMA class for the RP2040 microcontroller.
The class handles 3 scenarios at present
Transfers can happen at full bus speed or be paced by a DREQ channel.
This code includes a DMA timer class for pacing transfers at a fixed rate - see example code.
The methods can be given an optional handler for callback when a transfer completes when an IRQ is raised. Which IRQ is raised defaults to IRQ0, but can be passed in with the irq parameter.
