Change HID report parser so that it can calculate and record the sizes (IN, OUT and FEATURE) of each report within the device, by report ID. This will be required in host mode, so that the host can determine how many bytes of data must be read in for each report.

Add to MouseHostWithParser and KeyboardHostWithParser demos to print out the report sizes when a valid device is connected.
