484: Fix lifetime of pwmsequence buffer argument and clarity cleanups r=Dirbaio a=jacobrosenthal
Im not sure its UB to write to the sequence values struct after having started a pwm sequence.. but its against the ethos of the api I had in mind to monkey with it while its in motion.
~Use const generics to consume any size input instead of a borrow of slice~

It is basically impossible to directly convert that example to a sequence for various reasons. You cant have multiple channels on same buffer with one sequence instance for starters, also at that clock rate and max_duty 1 period is far longer than the 3ms it was using, which would require using a new max_duty and thus require regenerating the sine table which makes it not representitive of the original example anymore
455: simple_playback api from nrf sdk r=Dirbaio a=jacobrosenthal
Port of the nrf_drv_pwm_simple_playback call from the nordic sdk that allows you to set up a sequence to play across leds with no interaction necessary using the 'shorts' registers to trigger looping sequences

482: Add MCO peripheral. r=Dirbaio a=matoushybl
This PR adds an abstraction over STM32 RCC feature called MCO (Microcontroller Clock Output). The clock output can bind to several clock sources and then can be scaled using a prescaler.
Given that from the embassy ecosystem the RCC is generaly invisible to the user, the MCO was implemented as a separate peripheral bound to the pin where the clock should appear.

473: Replace rustflags with build.rs extra-link-args. r=Dirbaio a=Dirbaio
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.

Thanks to `@diondokter's` work on DPPI this was quite easy! :)
TODO:
- [ ] Add config option to enable 128mhz
- [ ] Add config option to unlock APPROTECT automatically.
- [ ] Add a way to boot net (config option or API?)
- [ ] Support WDT (there's WDT0, WDT1. Needs some refactor)
- [ ] Support NVMC
- [ ] Support TEMP
