v0.6.0 breaks omniauth due to transform_keys change #271
Description
The original worked:
https://github.com/oauth-xx/oauth-ruby/blob/de8c3861cf9669cfd10066479d4a3507d4d6a590/lib/oauth/consumer.rb#L98-L100
The new version does not:
https://github.com/oauth-xx/oauth-ruby/blob/62d3f3e52daa565a04e508df915456a21a7faf37/lib/oauth/consumer.rb#L106
It's because omniauth ultimately defines options as a Hashie::Mash not a Hash:
https://github.com/omniauth/omniauth/blob/master/lib/omniauth/strategy.rb#L547
https://github.com/omniauth/omniauth/blob/master/lib/omniauth/key_store.rb#L5
Hashie::Mash.new(one: "1", two: "2").transform_keys(&:to_sym)
{"one"=>"1", "two"=>"2"}
Hashie::Mash.new(one: "1", two: "2").to_hash.transform_keys(&:to_sym)
=> {:one=>"1", :two=>"2"}
