- Add `Process.project` and `rubanok_scope` methods to get the Hash of recognized params. ([@palkan][])

```ruby
class PostsProcessor < Rubanok::Processor
  map(:q) { block }
  match(:page, :per_page, activate_on: :page) { block }
end

PostsProcessor.project(q: "search_me", filter: "smth", page: 2)
# => { q: "search_me", page: 2 }

class PostsController < ApplicationController
  def index
    @filter_params = rubanok_scope
    # or
    @filter_params = rubanok_scope params.require(:filter), with: PostsProcessor
    # ...
  end
end
```

- Improve naming by using "processor" instead of "plane". ([@palkan][])
