This PR looks to solve issue #935 by Merging ExtractImagesNode into ImageSaver. Before we go ahead and do it, I assume we want ExtractImagesNode entirely removed since ImageSaver will now have all the functionailty and more of that previous node, opposed to just inheriting from that class.

Yes - there really isn't any reason to have two separate nodes that have similar, but not identical features. If image_saver supports saving at a particular rate, then it replaces the functionality of extract images node

Adding [a] new "fps" parameter to ImageSaver - when the parameter is set, we should setup a timer to fire and save images.

Do we need to make a TimerBase with a new callback, or does that seem excessive? Furthermore, if we had that callback we would need to get access to that image, from inside the constructor of ImageSaverNode

The end goal is to save at a fixed rate, regardless of the rate that the image shows up - I haven't come up with anything better than a ROS timer. The timer would require another callback (the function signature is different). When FPS parameter is set, we would want the image callback to save the latest image in a class variable so that the timer callback can access it (and that also means adding a mutex to protect that shared variable in case somebody loads the component with a multi-threaded executor).

We can leave fps_ as an int since there's no weird math similar to what was happening in secs_per_frame, right?

Revert "Initial Merging: Setting up ImageSaverNode"

This reverts commit 4534c95.

DisparityNode: replace full_dp parameter with sgbm_mode (ros-perception#945)

Previously, only the SGBM and HH modes were allowed

add invalid_depth param (ros-perception#943)

Add option to set all invalid depth pixels to a specified value, typically the maximum range.

 * Updates convertDepth parameter name and optimizes use of the parameter.
 * Updates PointCloudXYZ, PointCloudXYZI, and PointCloudXYZRGB with new invalid_depth parameter

Adding scale parameter to camera calibrator
