This PR adds validation when a CSV file contain duplication of headers
For example, give the following CSV file with the contents below:
name, email,age,name
User1,user@test.com,40,User2
In this case the value that is going to be set a property name in a dataclass is User2. It will overwrite the first value User1.
To avoid this problem, and data inconsistency, a validation is performed right when creating a instance of DataclassReader. If there are duplication a ValueError exception will be raised, showing which fields are duplicated.
In addition to the validation, it has been added support for skipping the validation, that is achieved by passing a keyword argument to the DataclassReader, like so:
