Separate query params from route params

[ig3]

As you know and documented, there was a potential collision between route and query parameters because they are both returned in the first argument to the route handler. For my own purposes I wanted to avoid this, so I separated the query parameters into a new second argument to the route handler, which now has four arguments. It reduces minified size to 689. But it is a breaking change.

As it is a breaking change, I anticipate that you may not want to merge this, which is fine. But I really appreciate your module so wanted to return this to you. In any case, thank you very much for rlite. I only just discovered it today, but it is (with this change) just what I need and more suitable than a dozen or so others I investigated: a little experiment that has gone very well indeed!!
