936: Add split() method to BufferedUarte in embassy-nrf r=ZoeyR a=ZoeyR
I haven't completed testing this yet. I'm creating this PR early so that I can get corrected if I went way off course.
This PR adds a `split()` method to `BufferedUarte` as discussed on matrix.

938: Do not use cfg_if for embedded-hal-async feature gates. r=Dirbaio a=Dirbaio
Old code used `cfg_if!` because rustc still parses code inside disabled cfg's, and Rust stable at that time couldn't parse the new GAT where-clause location. This is not the case anymore.

928: Ensure that the sampling is stopped r=Dirbaio a=huntc
Ensures that nRF saadc sampling is stopped and is awaited prior to exiting the two sampling methods. Not doing so causes a potential power drain and the potential for dropped buffer writes when having finished continuous sampling.

total_len is already rounded up, so the `+ 3` is not needed.
And even if it was, the calculation should have been `((total_len + 3) / 4)`.
`(total_len + 3 / 4)` is equivalent to `total_len` and can overflow
the slice, leading to a panic which can easily be triggered by sending
large ICMP ECHO packets to the device.

Call `config()` only once at construction not with every RX and TX operation.
The Lora-E5 only supports HP mode, use that instead.
The nucleo board supports both HP and LP and should continue to work.
The Seeed Studio Lora-E5 module only has two control pins.
With the `RadioSwitch` trait the user can implement any method required
by the module/board to control the TX/RX direction of the radio frontend.
