✨ charoption warning on running CLI for certain sources

[TheDSeraph]

Describe the solution you'd like
Create the new type for charoption items and/or provide instructions on how to exclude them so this warning wouldn't always be showing up for me. If creating a new type, they can live as a subfolder of Backgrounds.

Additional context
🔸 charoption is not yet an embeddable type: {"type":"statblock","tag":"charoption","source":"EGW","name":"Hollow One","page":182}
