#149 Add Feature Padding for delimited records

[telljimmy]

This is for adding the feature against the issue Support Padding via a Converted in the library #149

The only change done previous code is to move a chunk into a function. the long switch case for assigning converter is moved to GetConverter function so it can be used in 2 places.

Hi Jimmy

Thank you for your code and your explanation. We need to have a unit test to verify your contribution, would that be possible for you?

Thank you, Matthias
