Sometimes I want to use uint32 instead of big.Int in the auto-generated wrappers.
Currently, I need to add another struct.

Describe the solution you'd like

pkg/rpcclient/unwrap has a beautiful unwrapper
nspcc-dev/neo-go@6d20772714/pkg/rpcclient/unwrap/unwrap.go (L98)

Allow to use it from inside the autogenerator.
A possible value to use for a type in rpcbinding configuration is Integer:int64. Another option is base: Integer; Name: int64.
We may also have other types (e.g. uint32), the details can be discussed. E.g. have LimitedInt[T interface { ~int* }] and LimitedUint[T interface{ ~uint* }] in unwrap and reuse them.

Describe alternatives you've considered

Provide custom type/unmarshaler defined outside the generated code. With it, we can have SDK types reused in the autogenerated code for contracts.
