Add new sqlite extensions to allowlist

[Neo Dim]

Hi. I would like to use semantic search in one (or maybe couple) of my new packages for emacs. In latest emacs there is sqlite support, which  is great. I would like to use it with https://github.com/asg017/sqlite-vss extension. I checked it out and see that vector0 and vss0 not in allowlist. Can we add this extensions to allowlist? And can we use full path to extension when call `sqlite-load-extension`? I don’t think that this extensions will be system-wide.

Best regards,
