Support relative Content-Base paths

[kevmo314]

A camera I'm working with spits out Content-Base as a relative path instead of absolute. This change adds support for those by grafting in the scheme and host from the base URL if it appears to be a relative path.

Hello, i understood the change and i think it can be merged, but can you write the name of the manufacturer and model of the camera? in this way we are keeping track of why we performed these kind of compatibility-related changes. Thanks.

Yep, this specific camera is a Hanwha Vision XNV-6011: https://hanwhavisionamerica.com/product/xnv-6011/

I assume there may be other models with the same behavior but at least that's the one I'm working with right now :)
