Rule request: large tuples

[marcelofabri]

Tuples should have at most 3(?) members.

[doozMen]

In my opinion at least 4

[jpsim]

Could do warning at 3, error at 4. Configurable for sure.

Could also make exceptions for tuples defined and only used within the scope of a single function, where making a struct might not be worth it.

[marcelofabri]

Probably we should focus on validating function return types first and properties.

[mcfedr]

Sure this should be an opt in type of rule..

Updated swiftlint, project build fails...

[marcelofabri]

@mcfedr You can always disable a rule if you don't think it applies to your project or in this case tune in the limits.
