Description

Currently, subxt is missing support for integer types wider than 128bits. Smart contracts might use this type in their ABI, rendering subxt unable to interact with those contracts (they are supported inpolkadot-js).

Research direction

Start at codegen/src/types/type_path.rs#L236 and read the existing integer-type handling, then compare it with the 256-bit ABI definition in ink's contract_schema.json. Done means subxt can represent and interact with contract ABIs that use 256-bit integers, with the relevant existing checks passing.
