                 throws IOException
Returns the object of generic type T that is pem encoded in the supplier.

Parameters:
supplier - the input stream factory
marker - header that begins the PEM block
processor - how to parser the object from a byte array
Returns:
the object of generic type T which was PEM encoded in the stream
Throws:
IOException - if an I/O error occurs
