simple-dlna-browser: Add new package

[ghost]

Description of changes

Add a useful CLI script I found that's way light than VLC and other GUI apps since SSDP is pretty much a text-based protocol built on top of HTTP. It has no license attached so I marked it as unfree.
If the author adds a license, we will be able to specify it. @javier-lopez, would you be willing to add a license to your simple-dlna-browser script for its inclusion in NixOS?

Hello @LoveIsGrief , sure, would it be enough to add a header at the top of the script?

[javier-lopez]

I've licenced the script with the https://en.wikipedia.org/wiki/Fair_License , I hope this makes clear and easy the inclusion of the file, happy new year 🍻 , https://github.com/javier-lopez/learn/blob/master/sh/tools/simple-dlna-browser#L9
