Async buffered UART driver.
Note that discarding a future from a read or write operation may lead to losing
data. For example, when using
futures_util::future::select and completion occurs
on the “other” future, you should capture the incomplete future and continue to use
it for the next read or write. This pattern is a consideration for all IO, and not
just serial communications.
