* wip: timg embassy driver
- read_raw on timg renamed to now()
- timg initialized and stored in static for use in the embassy driver
- timg sets alarm value
- untested whether alarms actually trigger
* TIMG timer driver for esp32, esp32s3
- Adds the timg timer block as a time driver for embassy
- Not enabled on the C3 as it only has one timer block, better to use
systimer
- s2 example added but can't build due to atomic requirements in
futures-core
* Add S2 atomic support with emulation, fixup embassy support for the S2
* Move executor & static-cell to dev deps. Make eha optional
* Add c2 support, run fmt
* Update to crates.io embassy releases
* Update eha
* update timg time driver to new trait
* Remove exception feature of esp-backtrace and use the user handler for backtracing
* Add async testing workflow
* Update systick example
* Fix S2 examples
* Update xtensa-toolchain
* set rustflags for s2 target
* Disable systick for esp32s2 until we can fix the noted issues
* review improvements
- Fix intr prio array being off by one
- emabssy time prio interrupt set to max prio
- use cfg instead of feature for systick detection
* Update example time delays
