Small change to the camera capture template so that the saving of chessboard images can be easily toggled

Added template node for detecting aruco markers within a a camera image. Also adjusted to template_camera_capture node to save the camera image anytime OpenCV detects a calibration chessboard within the image.

Added servo driver to the template I2C internal node. At the same time added...

Added servo driver to the template I2C internal node. At the same time added convenience functions to the Pololu SMC and PCA9685 Servo drivers for the initialisation of respective chip

Fixed error in template_gpio launch file so that the line numbers parameter are now correctly added to the namespace of the resepctive nodes. Also some small corrections to the wiki docs.

Added driver vl53l1x and template I2C nodes

See merge request asclinic/asclinic-system!4

Added VL53L1X distance sensor to the template I2C node. Next step is simplify the template node code by moving the intialisation steps, and get distance mesurement steps into the vl53l1x.cpp class.
