Modify to use asyncasync

A changeover from embedded_hal::i2c::I2c to embedded_hal_async::i2c::I2c
including changes to all the relevant functions into async functions.

Tests have been updated to work using futures-test and embedded-hal-mock
with the embedded-hal-async feature.

Examples have been kept the same meaning they no longer compile.
Currently it doesn't _seem_ like the linux embedded hal can do async
i2c so maybe these should be re-written to use embassy?
