------
* Convert tri-codes from new format to old in Html PBP. Mappings stored in utils/tri_code_conversion.json.
* Added verbose option to top-level scrape functions
* Replaced default parser for HTML PBP with "html5lib" over "lxml". lxml was having issues with older games.
* Reduced chunk size in nhl.json_schedule.chunk_schedule_calls to 30 from 50. Was having some issues during tests.
