103a3305e2 Implements continuous sampling for the nRF SAADC
Implements continuous sampling for the nRF SAADC and also renames `OneShot` to `Saadc`. The one-shot behaviour is retained with the `sample` method and a new `run_sampler` method is provided for efficiently (i.e. zero copying) sampler processing. A double buffer is used for continuously sampling, which wlll be swapped once sampling has taken place.

A sample frequency is provided and will set the internal timer of the SAADC when there is just the one channel being sampled. Otherwise, PPI will be used to hook up the TIMER peripheral to drive the sampling task.

cef6158c31 Extend SAADC one shot support
One-shot mode now permits the sampling of differential pins, and the sampling of multiple pins simultaneously.

A new ChannelConfig structure has been introduced so that multiple channels can be configured individually. Further, the `sample` method now accepts a buffer into which samples are written.

Along the way, I've reset some default configuration to align with Nordic's settings in their nrfx saadc driver. Specifically, the channel gain defaults to 6 (from 4) and the time defaults to 10us (from 20us).

trait_alias seems unused. no idea why it's there.

3420cbf744 examples: Drop build-std = ["core"]
Previously the cargo configurations of all of the example projects had
`build-std = ["core"]`, which forces compilation of `core` as a
code-size optimisation. However, this is strictly unnecessary and will
currently break for users who do not use `rustup` directly (e.g. nix
users).

1b9d5e5071 Multi Producer Single Consumer channel
An MPSC inspired by Tokio and Crossbeam. The MPSC is designed to support both single and multi core processors, with only single core implemented at this time. The allocation of the channel’s buffer is inspired by the const generic parameters that Heapless provides.

Resolves #187

Like the stm32 driver, this has both a non-blocking and blocking API, and implements `rand_core::RngCore` for the blocking API.
