Update to embedded-hal v1.0.0

[Sycrosity]

• Updates Cargo.toml to eh v1.0.0
• Updated embedded-hal-mock to v0.10.0
• Replace existing trait impls with eh v1.0.0 ones

This is by no means without it's difficulties - the AdcProxy struct must be dropped, as eh v1.0.0 does not contain traits for Adc, and the tests have not yet been updated - I don't have the time at this moment to implement those.
