No way for user to get system clock frequency from embassy-stm32

[dlaw]

After configuring clocks with embassy-stm32, peripheral clock frequencies are available through the .frequency() methods of the corresponding peripherals. However, there seems to be no way for user code to find out the system clock frequency.

Internal embassy-stm32 code is able to use the private get_freqs() method for this:
https://github.com/search?q=repo%3Aembassy-rs%2Fembassy%20unsafe%20%7B%20crate%3A%3Arcc%3A%3Aget_freqs()%20%7D.sys&type=code

Would it be possible to provide a public RCC method which returns the system clock frequency?

I would be happy to attempt the implementation if this is deemed desirable.

Ah yes, I've run into this a couple of times as well. Would be nice to get access to the clocks (also more than just the system clock).
I guess the reason it's not public is because it's not considered a stable API.
