Changes for version 0.188 - 2017-10-27
- reduce sleeps between polls during wait() by using Time::HiRes and a sub-second poll time.
- if auto_start is specified, a ds9 process will be created if one can't be connected to.
- if kill_on_destroy is specified, the ds9 process will be terminated when the Image::DS9 object is destroyed.
