build(deps): update embedded-hal-bus requirement from 0.1 to 0.2

[dependabot[bot]]

Updates the requirements on embedded-hal-bus to permit the latest version.

Changelog

Sourced from embedded-hal-bus's changelog.

v0.2.0 - 2018-05-12

Added

• A ToggeableOutputPin trait has been added. This trait contains a single method: toggle that can be used to toggle the state of a push-pull pin.

Changed

• [breaking-change] The signature of CountDown.wait changed; it now returns nb::Result<(), Void>. Where Void is the stable alternative to the never type, !, provided by the stable void crate. Implementations of the CountDown trait will have to be updated to use the new signature. With this change this crate compiles on the stable and beta channels.

• [breaking-change] the OutputPin.is_{low,high} methods have been moved into its own trait StatefulOutputPin and renamed to is_set_{low,high}.

• It has been clarified in the documentation that OutputPin must be implemented for push-pull output pins (and e.g. not for open drain output pins).

v0.1.1 - 2018-02-06

Added

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
