* Rework timer_queue and monotonic architecture
Goals:
* make Monotonic purely internal
* make Monotonic purely tick passed, no fugit involved
* create a wrapper struct in the user's code via a macro that then
converts the "now" from the tick based monotonic to a fugit based
timestamp
We need to proxy the delay functions of the timer queue anyway,
so we could simply perform the conversion in those proxy functions.
* Update cargo.lock
* Update readme of rtic-time

Previously, the stm32 monotonics only compiled for some chip families. For
example, stm32g081kb worked, but not stm32f407*.
The stm32-metapac does not directly unify peripheral names between the
many stm32 families, but provides tools for build scripts to generate
code that uses the right names for the selected chip. Use that mechanism
instead of targeting a specific family.
Counting at 1 kHz, 32 bits for counting ticks is not enough to ensure
monotonicity for more than 50 days. Add a feature to change the backing
storage to 64 bits.
Some hals implement traits for embedded-hal version `=1.0.0.alpha.<not 9>`, which is
explicitly incompatible with the version `=1.0.0.alpha.9` which embedded-hal-async
depends on. Making the dependency optional allows downstream projects to include
rtic-monotonic without requiring that all of their other libraries also implement
that specific version of embedded-hal 1.0
