Bulk permission check

[inabhi9]

Is your feature request related to a problem? Please describe.
We often require to query multiple permission on multiple resource for a subject and currently Permify doesn't have any way to do it in single request and multiple requests are not efficient.

Describe the solution you'd like
It would be great if Permify can provide an endpoint for bulk permission check.

Describe alternatives you've considered
I checked subject permission list and found it uses same check() internally for all the actions for a resource and a subject which is not the best but better than multiple requests in some cases.

However, it's great if Permify can implement some more efficient technique to do reverse lookup.
