Description

It introduces the writeParams calls according to #241. It is basically a view call done before the actual transaction to gather all the important information for the offchain call.

This is how the interfaces are currently implemented. Ideally, the WildcardWriting interface, which only has the writeParams call, would get implemented within the IWriteDeferrral interface proposed by the EIP-5559.

Disclaimer:

The fixing of tests lead to a small refactor where the metadata tests got moved to their own file to simplify test logic.
