Add APIs to get extrinsic/distortion matrix and timestamp, etc.

[davidliyutong]

Timestamps are helpful for researchers of robotics

Changes:

• [feature] add get_timestamp_usec method to capture
• [feature] add get_device_timestamp_usec to capture
• [feature] add get_system_timestamp_nsec to capture
• [feature] add get_extrinsic_matrix to calibration for getting extrinsic matrix of cameras
• [feature] add get_distortion_parameters for getting distortion parameters of cameras

Here is an example to test:

import pykinect_azure as pykinect
pykinect.initialize_libraries()

def test_new_api(path: str):
    pb: pykinect.Playback = pykinect.start_playback(path)
    while True:
        ret, capture = pb.update()
        if ret:
            print("Extrinsic Matrix: ", capture.calibration.get_extrinsic_matrix())
            print("Distortion Matrix: ", capture.calibration.get_distortion_parameters())
            color_obj = capture.get_color_image_object()
            print("timestamp usec: ", color_obj.get_timestamp_usec())
            print("Device timestamp usec: ", color_obj.get_device_timestamp_usec())
            print("System timestamp nsec: ", color_obj.get_system_timestamp_nsec())
        else:
            break
