Data type judgment and optimization

[AZQD]

If shorthandblacklist, the second parameter of the tranform function, misuses a string, such as' fontmargin ', abbreviations are also allowed.

Maybe it's more rigorous to add typescript or verify data type here.

Yeah, that's a good should. Maybe we should remove the default argument, then Array.isArray(shorthandBlacklist) && shorthandBlacklist.includes(…) - we should get a perf win from that too
