[Feat] Rails integration to set default inflector

[okuramasafumi]

This is a temporary implementation of how to automatically set default inflector with Rails.
I haven't tested with user-defined inflector setting.

This seems fine to me as an alternative to #274. You could consider Alba.inflector ||= :active_support in case the user somehow wants to set it a different way and this runs first. Note in the other PR I did before_initialize, but I think this is fine and probably more typical anyway.

If you want help testing, let me know. I have a few sample Rails and Hanami apps I was using to test this earlier as well.

[okuramasafumi]

@trevorturk I think this works OK, could you try it in real Rails apps? If this works I'll add Hanami integration in separate PR.

[trevorturk]

Yes, this works perfectly for me. It's set by default, and if you want to configure Dry::Inflector it works as well:

irb(main):001:0> Alba.inflector
=> Alba::DefaultInflector

#...and with
# config/initializers/alba.rb
Alba.inflector = :dry

irb(main):001:0> Alba.inflector
=> #<Dry::Inflector>

@trevorturk Could you also check if it works with user-defined initializer? For example,

# config/initializers/alba.rb
Alba.inflector = :dry

[trevorturk]

Yes, sorry if I wasn't clear about it, but I did test that. (See my code sample above, I should have broken it into two examples, but I did try with and without an initializer. It works great in both cases.)

Awesome, thank you!
