- Allows classes to handle vendor requests.
- Allows classes to use a single handler for multiple interfaces.
- Allows classes to access the other events (previously only `reset` was available).
1142: More rp2040 BufferedUart fixes r=Dirbaio a=timokroeger
* Refactor init code
* Make it possible to drop RX without breaking TX (or vice versa)
* Correctly handle RX buffer full scenario

modify RP2040 adc example to get inside biased bipolar diode voltage,
then convert this temperature sensor data into Celsius degree,
according to chapter 4.9.5. Temperature Sensor in RP2040 datasheet.
984: rp pico async i2c implementation r=Dirbaio a=jsgf
This implements an interrupt-driven async i2c master. It is based on https://github.com/embassy-rs/embassy/pull/914, a bit of https://github.com/embassy-rs/embassy/pull/978 and `@ithinuel's` https://github.com/ithinuel/rp2040-async-i2c.git
This is still work-in-progress, and is currently untested.
1006: Removes some of the code duplication for UarteWithIdle r=Dirbaio a=huntc
This PR removes some of the code duplications for `UarteWithIdle` at the slight expense of requiring a split when using idle processing. As the nRF example illustrates though given the LoC removed, this expense seems worth the benefit in terms of maintenance, and the avoidance of copying over methods. My main motivation for this PR was actually due to the `event_endtx` method not having been copied across to the idle-related code.
Tested the uart_idle example on my nRF52840-dk, and from within my app. Both appear to work fine.

Simple example exercising an mcp23017 GPIO expander, configured on
RP2040 GPIOs 14+15 (i2c1) with 8 inputs and 8 outputs. Input bit 0
controls whether to display a mcp23017 register dump.
This is an interrupt-driven async i2c master implementation. It makes as
best use of the RP2040's i2c block's fifos as possible to minimize
interrupts.
It implements embedded_hal_async::i2c for easy interop.
WIP async impl
It currently contains whoever was first to write some code for the crate,
even if many more people have contributed to it later.
The field is "sort of" deprecated, it was made optional recently:
https://rust-lang.github.io/rfcs/3052-optional-authors-field.html
Due the the reasons listed there I believe removing it is better than
setting it to generic fluff like "The Embassy contributors".
Rustflags apply to ALL the crates in the graph, while we only need
them for the toplevel crate which is the only one getting linked.
Rustflags are not equal for all crates, this caused cargo to re-build the
same dependency crate multiple times uselessly. After this change, deps
are reused more, making builds faster.
Note that this only applies when sharing the target/ dir for multiple crates
in the repo which is not the default.
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).
