858: embassy-stm32: Simplify time r=Dirbaio a=GrantM11235
- Remove unused `MilliSeconds`, `MicroSeconds`, and `NanoSeconds` types
- Remove `Bps`, `KiloHertz`, and `MegaHertz` types that were only used
for converting to `Hertz`
- Replace all instances of `impl Into<Hertz>` with `Hertz`
- Add `hz`, `khz`, and `mhz` methods to `Hertz`, as well as
free function shortcuts
- Remove `U32Ext` extension trait

810: Takes care of power for nRF USB devices r=Dirbaio a=huntc
Modifies the usb-serial example to illustrate how to setup USB for situations where the USB power can be detected and removed.
Gaps:
~~* No support for the nrf-softdevices as yet, although this should be possible via another constructor.~~
* No support for the nrf5340, although this should be possible via USBREG.
The change is tested and appears to work. Some notes:
* There's an existing field named self_powered as a UsbDevice field. It doesn't ever appear to get set. I'm wondering if this field is intended to signal that a device has the nRF VBUS power situation or not. I'm not presently using it.
* The new PowerDetected event is generated on the bus initially in situations where just new is used i.e. without power management, including on STM. We can therefore rely on this event always being generated.
Old description:
~~EnabledUsbDevice is a wrapper around the `UsbDevice` where its enablement is also subject to external events, such as `POWER` events for nRF. It is introduced generically to support other platforms should they also require external signaling for enablement.~~

Eliminated a signal by using a simpler trait method that returns whether VBus power is available. Also includes a UsbSupply that can be signalled for use with the nRF softdevice. Includes the requirement for waiting for power to become available.

817: Added a pubsub channel implementation r=lulf a=diondokter
This is similar to Tokio's Broadcast channel, except that it doesn't allocate.
The publishers and subscribers are dynamic. They use an &dyn channel reference because it's really annoying to have to specify the mutex and const generics every time.
Do we need fully generic types as well?

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".
