Last Name is first when the Last Character is an Initial

[enkodellc]

Last Name is first when the Last Character is an Initial. I added the tests and they all passed. These types of names are found in public records and that is what I am parsing so it should be beneficial to others. If there is something wrong please let me know. Maybe it could have done with Prefer / Config but this seems fairly straightforward. Thanks for the repo!

Thanks! I'll take a look soon and after merging will update the nuget.
