Please complete the following tasks

winnow version

0.5.34

Describe your use case

"alt((A, B, C))" signifies that one of multiple combinators will be matched. Can weights be assigned to the combinators within alt so that those with higher hit rates are prioritized for parsing, rather than always parsing them in sequential order?

Describe the solution you'd like

no

Could you describe the use case for why an explicit weight would be use rather than the implicit one based on the ordering?
