Provide custom URL to DPDB

[danrossi]

There is an enforcement to load a remote json. However it is out of date to the github version and missing Samsung S8 (webvr fully functional with flags enabled).

Needs an option to use updated cache or custom url ?

Can you check immersive-web/webvr-polyfill-dpdb#23 (comment)

and, yes, we can support a custom URL to use instead

That is for S8+ not S8. different codes. S8+ has a bigger screen. i had to add it to a custom device json. according to the code the url is a constant.

this has since been updated. we should still keep this issue open to allow providing a different URL to the JSON file for a custom DPDB.

It's ok thanks for that. I had to fork and modify myself to get S8 working.

Updating issue title -- please update with a new issue if you're still seeing issues with S8 after updating. Thanks!

Added in cardboard-vr-display 1.0.1, and webvr-polyfill 0.10.0, there's now a DPDB_URL config option
