Attribute type seems not to work and the attribute is still not casted

[Piioo]

Environment

Provide at least:

• Ruby 2.6
• Symmetric Encryption Version -> 4.3.2
• Rails 6

Expected Behavior

When I define an attribute in the model to be encrypted with type definition, then it should be casted to this type

attribute :foo, :encrypted, type: :integer

When I assign to foo a string number, it should be casted to integer.

This is what is described here: http://encryption.rocketjob.io/frameworks.html

Actual Behavior

o = Object.new
o.foo = '124'
o.foo => '124'
