Allow for multiple Tenant ID's to be included

[inctor]

In some cases, we've seen the requirement for allowing multiple tenants to be included on the same platform/instance.

This modification should not have any implications on existing implementations, and should only extend the current functionality.

Since it's already allowed to use addTenants with an array, it makes sense, that it should also scope by multiple ID's.

Could be extended to allow for a collection object, instead of only arrays if it has potential.

Granted the "is_array" statement may be slower in older versions of PHP, could be switched out in favor of
(array) $id === $id

But since PHP7, the performance difference between them is really small, even on large test-sets.

@inctor this looks similar to my pull-request #17 which was rejected. Your implementation is a lot less invasive than mine, however it looks like there are no plans to support multiple tenants.

[inctor]

@inkadnb Yeah seems like it.
We've however stopped using the composer version of this package, and made the modifications to our own version, so we ensure that we have the needed functionality.

I know the functionality might be beyond the "scope" of this package, however, we have some specific needs for unique clients, that needs this functionality.

Eventually we'll write our own scope-package to handle this, but for now, we're just using a modified version of this package to accommodate our current needs.

@inctor that's what we've ended up doing as well. Basically, we've made our own implementations of the most recent two pull-requests. Our main use-case is for administration, being able to scope multiple tenants at once and also being able to support tenant hierarchies. We also make tenant_id nullable so that certain data can span across all tenants.

Yeah, unfortunately, this is out of scope for this package. This package is meant specifically for scoping to a single tenant at once.
