Add pagination members to struct via Macro

[tluijken]

For pagination, we always add the same 3 members to our structs. Since this is very repetitive, we could leverage a Macro here to omit boiler plated code.

However, it's not possible to leverage our current proc-macro for this. We should leverage an attribute-proc-macro.
