`sqlc.(n?)arg` panics when 0 arguments are passed in

[ryan-berger]

Version

1.13.0

What happened?

I accidentally passed 0 arguments into sqlc.narg and received the following panic:

goroutine 1 [running]:
github.com/kyleconroy/sqlc/internal/sql/validate.ParamStyle({...., ......})

Which comes from this line:

https://github.com/kyleconroy/sqlc/blob/c2dcd56a5d8b2a3b2fa9c7f6545d0b1d5555be29/internal/sql/validate/param_style.go#L19

Although this is invalid input, it would be nice to have an error message printed out.
