* Force frame pointers for RISC-V chips
* Various dependency updates
* Update to latest published PACs and resolve build errors
* Top-level `README` updates
* Further clarify when `RUSCT_BOOTSTRAP=1` is required
* Fix Async UART
The uart handler was `writing` to the enable register instead of
`modify`, which meant any wake would see the cleared enabled bit and
think the event had occurred. This wasn't seen before the split of uart
because it was only possible to listen to one thing at a time.
This PR also removes the ReadBufferFull error in favour of returning the
max bytes in the buffer.
The serial examples has been updated to actually have some cross task
communication.
