tsvector helpers + RBS type signatures

• SearchCraft::TextSearch module added to Builder which provides tsvector helpers. See test_text_search.rb for examples.

• RBS type signatures

• Convenience Config.explicit_builder_classes = {"Builder" => "Model"} if you need to explicitly describe your Builder + Model classes and they are 1:1

• Override default table name for ViewHashStore with:

  SearchCraft.configure do |config|
    config.view_hash_store_table_name = "'my_schema'.'my_table_name'"`
  end

Fixes:

• Fixes for users of SearchCraft.config.explicit_model_class_names on initialization
