DDC/CI command request and response types.

Delay	A type that can help with implementing the DDC specificationed delays.
VcpValue	VCP Value

ErrorCode	DDC/CI protocol errors
VcpValueType	VCP feature type.

DELAY_COMMAND_FAILED_MS	DDC delay required before retrying a request
I2C_ADDRESS_DDC_CI	DDC/CI command and control I2C address
I2C_ADDRESS_EDID	EDID EEPROM I2C address
I2C_ADDRESS_EDID_SEGMENT	E-DDC EDID segment register I2C address
SUB_ADDRESS_DDC_CI	DDC sub-address command prefix

Ddc	A high level interface to DDC commands.
DdcCommand	A (slightly) higher level interface to `DdcCommandRaw`.
DdcCommandMarker	Using this marker trait will automatically implement the `Ddc` and `DdcTable` traits.
DdcCommandRaw	Allows the execution of arbitrary low level DDC commands.
DdcCommandRawMarker	Using this marker trait will automatically implement the `DdcCommand` trait.
DdcHost	A DDC host is able to communicate with a DDC device such as a display.
DdcTable	Table commands can read and write arbitrary binary data to a VCP feature.
Eddc	E-DDC allows reading extensions of Enhanced EDID.
Edid	A trait that allows retrieving Extended Display Identification Data (EDID) from a device.
