Premint - get supported premint signature version (#303)

Added method `IZoraCreator1155PremintExecutor.supportedPremintSignatureVersion(contractAddress)` that tells what version of the premint signature the contract supports, and added corresponding method `ZoraCreator1155Impl.supportedPremintSignatureVersion()` to fetch supported version.  If premint not supported, returns 0.

+Premint - added method getSupportedPremintSignatureVersions(contractAddress) that returns an array of the premint signature versions an 1155 contract supports.  If the contract hasn't been created yet, assumes that when it will be created it will support the latest versions of the signatures, so the function returns all versions.
