Support pusher end-to-end encryption

[it-can]

Would be nice to have support for end-to-end encryption

So this is just to get it working client side right? Because you can already add the options server-side in your config.

yeah this seems to be possible within laravel,

laravel/framework#31559

But I think we also need an option to subsribe to private-encrypted- channels... this is not possible in echo as far as I know now...

[driesvints]

I'll mark this as an enhancement for now. Feel free to pr.

ok will try to find some time to create a PR...

@driesvints ok added a PR, can you take a look if I did it correct?

@driesvints: I believe this issue can be closed? "laravel/echo" 1.7.0 and "laravel/framework" 6.17.0 changes allow private encrypted channels.
