Add resolveUrl prop

[stefan-krajnik]

Currently there's no way to use e.g. signed urls for uploaded files.

A callback function resolveUrl: (src: string) => Promise<string> would solve the issue. Or if you have any other idea we can discuss in comments.

@stefan-krajnik thank you for feedback. Do we need a callback url? In what cases do you use it?

@hunghg255 The use case I have is, that all files are uploaded to aws s3 bucket, not all files are public, so I need to generated signed url.
