Add video upload support Chevereto

[Dalethium]

Chevereto now supports video uploads, It would be fantastic if ShareX could support that too, for that upload site.

I'm available for any technical assistance needed for making this a reality.

{
  "Version": "16.0.4",
  "DestinationType": "FileUploader",
  "RequestMethod": "POST",
  "RequestURL": "https://DOMAIN/api/1/upload",
  "Headers": {
    "X-API-Key": "KEYHERE"
  },
  "Body": "MultipartFormData",
  "FileFormName": "source",
  "URL": "{json:image.url}",
  "ThumbnailURL": "{json:image.thumb.url}",
  "DeletionURL": "{json:image.delete_url}"
}

I've been using this as a custom uploader in the meantime. It works fine. Hopefully, this can help it be implemented a bit easier.
