Add support for external .ani animations | Plumber

[JokanJan]

When importing v models for csgo, the animations are blank and the number of animations imported in comparison to older versions of the plugin is incorrect. There is no error reported by the console, and there is no abnormality in the import of w models and character models.

These are probably animations that are in external .ani/.mdl files instead of the main .mdl. Those are currently unsupported, I will add a warning about this to the console.

The warning is implemented in latest beta release.

These animations are probably stored externally in separate .ani files. Those are not currently supported but I'll probably add support for them later.
