* Update nozzle_scrub.cfg
Fix error in script defining random selection of bucket halves for purging. Small speed unit correction. (thanks Deutherius#3295 on VD discord for pointing these out)
* Fix incorrect syntax
* Fix incorrect range definition
Range was incorrectly defined, leading to bucket_pos not actually being randomly selected.
* Add several features
- Scrubbing location and direction now follow the randomized location of left and right bucket.
- Added filament retract after a purge.
- Added a dwell/wait parameter after a purge for particularly oozy filaments.
