This makes the contracts more consistent with OpenZeppelin examples. No signatures are changed, but there is one slight change in behavior: if you specify a "base URI", then individual token URIs are always understood to be a suffix for that base URI. The previous contract would ignore the base URI when a token URI was specified. Signed-off-by: Andrew Richardson <andrew.richardson@kaleido.io>

There is no change to the external function signatures, but this brings us more inline with the latest ERC1155 examples from OpenZeppelin.
The sample now extends ERC1155URIStorage for token URI functionality. There is one slight change in behavior: if you specify a "base URI", then individual token URIs are always understood to be a suffix for that base URI. The previous contract would ignore the base URI when a token URI was specified.
Old contracts will be unchanged, and no functionality in the connector or FireFly will be changed by this new behavior - but users of the contract will need to plan accordingly for how they specify base URI and token URIs.
