feat: Support batch enforce and add corresponding test.

Support batch enforce and add corresponding test. #166

It used async stream to implement BatchEnforceAsync except NET452.

It added BatchEnforceParallel in Enforcer without a corresponding interface in IEnforcer. I'm not sure about the design here. What I think is that its only a special implementation so that adding it to IEnforcer may mean little.

As for the extension, I only provide methods which accept generic type inherited from IRequestValues. The reason is that if I provide similar API with that of EnforceExtension.GenericEnforce, users need to pass several IEnumerable, such as e.BatchEnforce(List<T1>, List<T2>, List<T3>). Thus, consistency of the parameters is not actually ensured, which I think may not be a good practice. Please give some suggestions about it.

I'll PR a benchmark of it if the design is approved finally.
