v1.1.0

Adds offset_page pagination strategy:

Pagination strategy: offset_page

The offest_page strategy is based on the page strategy with the only difference
that the pages are counted from 0 onwards (not from 1).

# app/models/transaction.rb

class Transaction < DHS::Record
  configuration pagination_strategy: 'offset_page', pagination_key: 'page'

  endpoint '{+service}/transactions'
end

# app/controllers/some_controller.rb

}
