Implement parser for BetonQuest items

[Antimony-Sb]

Hi,
I’d like to request that BetonQuest items can be referenced in the hmc plugins.
I mainly would want to use the BQ items in the hmcrewards plugin.
I’m not sure what else should be included here, so I’d just leave the link to the BetonQuest API documentation:
https://betonquest.org/2.0-DEV/API/Overview/

Looking at the BetonQuest docs, there isn't any mention of a location to get an item (nor looking at the code provides any answers). I would be more than happy to get more information to add this, or I would also accept a PR
