[Group Check] v1.12: Add support for Pathfinder Official sheet (#848)

* [GroupCheck v1.11]

- Replaced sending a single message for all tokens by mutliple concurrent messages. This should help as a workaround to a Roll20 bug which does not display inline rolls correctly if there are too many of them in a single API message.
- Changed default for --process to true (since the bugfix can only work for --process).

* [GroupCheck] Simplify Promise code

* [Group Check] v1.12
