Useful information to include:

• Explanation of how the feature/change should work.
• Some rationale/use case for a feature. My general approach to designing new features is to ask yourself "what issue are we trying to solve" and then "is this the best way to solve this issue?".

I tried to write storage server and related things for some time. One of strange things i encountered: turtles dont have methods to transfer items, which makes it impossible to transfer items strait between turtles requiring some buffer storage between.
I thing that making peripherals have multiple types will solve that issue, so then wrapping turtle as peripheral methods for both pc and generic inventory are exposed.

There probably exist similar issue when block have both fluid and item storage, but i am not checked that.

Thanks for the issue! I think this is a duplicate of #1392, so going to close it in favour of that.
