Split-PDF is not possible for PDFs with password

[AndreasLuebbers]

It would be great if you could implement a new parameter "-password" which is used to open the pdf and split the pdf.
When I Try it there comes this error:
WARNING: Split-PDF - Error has occured: Exception calling ".ctor" with "1" argument(s): "Bad user password. Password is not provided or wrong password provided. Correct password should be passed to PdfReader constructor with properties. See ReaderProperties#setPassword() method."
