Add camera ENUM for changing sensor line time vs bit depth

[adamkglaser]

New finding from camera manufacturer which is important (and could indirectly modulate the line time). The line time of the camera actually depends on the bit depth setting (imposed by the actual Sony IMX411 camera sensor chip build).

eGrabber frame rates are limited as follows, where the line rate can be reverse calculated as:

line rate = 1 / (10760 lines x frame rate) [sec]

bit depth	frame rate [hz]	line rate [μs]	raw data rate [MB/sec]	16-bit packed data rate [MB/sec]
16	2.045174360275268	45.44	618	618
14	4.598678588867187	20.21	1215	1388
12	6.195786952972412	15.00	1403	1871

** Note: the Sony IMX411 sensor has 10640 lines readout per image, but 10760 actual rows which are read (the extra 120 are not output into the image).
