Multiple decorator error when using @schema.output

[sT0v]

This is pretty self-explanatory, but just wanted to make sure that this was in fact illegal?

@schema.output(
  ("ticker", "str"),
  ("fee", "float")
)
@tag(table_type="reference")
def ref_table_1() -> pd.DataFrame:
  ...

ValueError: Got multiple decorators for decorator @<class 'hamilton.function_modifiers.metadata.SchemaOutput'>. Only one allowed.

Yeah, this should work... I think there's some bug in how we handle this:

• there's ohnly one schema.output there
• But it's triggering this...

  hamilton/hamilton/function_modifiers/metadata.py

  Line 242 in acd2fc7

  return False

What's happening is it's going by lifecycle step, but it should really go by class... The SchemaOutput is not respecting the contract (E.G. that you can't override allow_multiple). But we should clarify this, or just allow multiple and have a check on the tag decorator to ensure they don't overwrite.
