Added query rate configuration for UBI0 tactile sensors
Added a customizable launchfile in sr_config
Launchfile now launches two hand drivers with the appropriate parameters for each of them
Remapping diagnostics to push them to right namespace
Added namespace arg in default controllers launchfile. Added tf_prefix to sr_edc.launch
Created the necessary files for a second hand. They have been put inside a directory called lh that stands for left hand, but the name could be chaged, and then the config_dir argument should be changed accordingly. The right hand in thes case remains in the same directory as it did in previous versions, therefore the config_dir argument will be an empty string. It's worth noting that more than two hands could be use by adding more configuration directories to this setup
Motor board controller parameters file path is also prefixed with config_dir now
Modified motor mapping for the left hand
Adding some utility launchfiles
