Feature skip_preload

[OuYangJinTing]

Thank for this gem and all contributors. This gem is great, auto-preload config is convenient.
But sometimes we don’t need to loads all records association auto matically, just load AR own associations.
This PR is trying to deal with this scene.

1. I don't quite understand what this does
   Imagine you are writing README section about this new method, what would you write?

2. Commit Fix sql matching seems strange as the previous commit got a pass in CI build
   Or is it just a refactor (in spec)?

The #skip_preload is for avoid preload all associations at special scene.
I try to udpate README, #skip_preload add to Auto preloading section.
About Fix sql matching commit, some rails version CI build is failed, it has two different SQL cases.

SELECT "posts".* FROM "posts" WHERE "posts"."user_id" IN (1, 2)
or
SELECT "posts".* FROM "posts" WHERE "posts"."user_id" IN (?, ?)  [["user_id", 1], [user_id", 2]]

I think your README update is incomplete/broken...

Very much your remind. I'm so sorry, ignored skip_preload method call.
