Sync Roles by IDs

[AlexJFox]

Love this bot, it's the only thing of its kind doing this I can find, so thank you for creating it.

I'd like it to be possible to be able to map a source role to a target role (or roles) by ID, so it doesn't rely on name matching, and more importantly, doesn't try to apply every role it can find by name match.

I have started working on this feature, but it is not ready yet.
