does not validate if the uploaded file is a File (not a base64 content)

[RHRiday]

I get this error when I upload a File instead of converting the file into a base64 decoded file.
TypeError: Crazybooot\Base64Validation\Validators\Base64Validator::convertToFile(): Argument #1 ($value) must be of type string, Illuminate\Http\UploadedFile given
even when I add 'string' to the validation rule, it does not check whether it's a base64 content or not. My suggestion is it should check whether the given data is a base64 content first then do other validations.
