Permission policy updates

[VijoPlays]

Just integrated 'secure' into my flask app, and the documentation has been very useful (thank you!). One adjustment I'd make to the docs, is to mention that leaving a policy empty, like

    secure.PermissionsPolicy()
    .accelerometer()

means it's being disabled.

The main reason I made this issue though, is the missing permission policies.

I don't know whether they are new or not, either way, would be dope to have them added to 'secure' as well.

Apart from the proposed/experimental tabs, the ones I've found are missing are the following ones:

• [ ] battery
• [ ] cross-origin-isolated
• [ ] display-capture
• [ ] execution-while-not-rendered
• [ ] execution-while-out-of-viewport
• [ ] navigation-override
• [ ] publickey-credentials-get
• [ ] screen-wake-lock
• [ ] web-share
• [ ] xr-spatial-tracking

And I assume

• [ ] Values
• [ ] vr

are outdated, since they also throw errors when I attempt to use them?

And I also just checked, the "ambient-light-sensor" is misconfigured slightly:

ambient-light-sensor =()

The space between the brackets and the ALS make it throw an error (and the speaker one throws a warning (not recognized), though that might just be an issue on my end).

And the CSP header is also missing the

"prefetch-src"

attribute.

Again though, the library is very nice thus far!
