Feature: add support for Extended Controls (VIDIOC_S_EXT_CTRLS) #39

Currently set_control uses VIDIOC_S_CTRL however sometimes it is also useful to use VIDIOC_S_EXT_CTRLS: https://www.kernel.org/doc/html/v4.9/media/uapi/v4l/extended-controls.html

Would you be willing to take a stab at the implementation? This functionality is not hugely important to me right now, so not sure when I would get time for it.

I can see that rscam https://github.com/loyd/rscam/blob/master/src/lib.rs#L495 only uses VIDIOC_S_EXT_CTRLS. Maybe lets keep it as a placeholder for now.

Should be closed by https://github.com/raymanfx/libv4l-rs/pull/41, which has been merged today. Let me know if anything else is missing.
