stmhal: Overhaul UART class to use read/write, and improve it.v1.3.4
UART object now uses a stream-like interface: read, readall, readline,
readinto, readchar, write, writechar.
Timeouts are configured when the UART object is initialised, using
timeout and timeout_char keyword args.
The object includes optional read buffering, using interrupts. You can set
the buffer size dynamically using read_buf_len keyword arg. A size of 0
disables buffering.
