Add a Split Large Messages plugin

### Plugin Description I feel like vencord should add a plugin that automatically splits large messages. FakeNitro does not bypass the character limit and I feel like it would be nice and a hell of a lot easier. ### Existing Plugin for other mod https://betterdiscord.app/plugin/SplitLargeMessages ### Request Agreement - [X] I read the above and made sure my plugin is possible and allowed - [X] I checked the [existing plugins](https://vencord.dev/plugins) and made sure my plugin doesn't already exist - [X] I [searched the existing issues](https://github.com/Vencord/plugin-requests/issues?q=is%3Aissue) and made sure a similar request doesn't already exist
