terms don't include transfer type anymore since its extracted via bytes length

I think writting this this way:
if (isBatch_) {
if (selector_ != IERC1155.safeBatchTransferFrom.selector) {
revert("ERC1155TransferEnforcer:unauthorized-selector-batch");
}
_validateBatchTransfer(_delegationHash, callData_, permittedTokenIds_, permittedAmounts_);
} else {
if (selector_ != IERC1155.safeTransferFrom.selector) {
revert("ERC1155TransferEnforcer:unauthorized-selector-single");
}
_validateSingleTransfer(_delegationHash, callData_, permittedTokenIds_[0], permittedAmounts_[0]);
}
Should be slightly better gas wise.
