laser_filters

* [intensity_filter.h] fix: check if cur_bucket value is out of index of histogram array
* [intensity_filter.h] refactor codes; clearify by using boolean to enable/disable displaying histogram
* scan_to_scan_filter_chain: make tf filter tolerance customizable
  0.03 is completely arbitrary and too small in my case.
* scan2scan filter: only publish result if filter succeeded
* added cartesian box filter
* add check inf or nan of input laser_scan intensities
* scan_to_scan_filter_chain: Only subscribe to /tf if requested by parameter
