Async I2C API

This API supports 7-bit and 10-bit addresses. Traits feature an AddressMode marker type parameter. Two implementation of the AddressMode exist: SevenBitAddress and TenBitAddress.

Through this marker types it is possible to implement each address mode for the traits independently in embedded-hal implementations and device drivers can depend only on the mode that they support.

Additionally, the I2C 10-bit address mode has been developed to be fully backwards compatible with the 7-bit address mode. This allows for a software-emulated 10-bit addressing implementation if the address mode is not supported by the hardware.

Since 7-bit addressing is the mode of the majority of I2C devices, SevenBitAddress has been set as default mode and thus can be omitted if desired.
