docs: Changes the current file position of this file.
          
          The file current position always applies to the :py:func:`IFile.read` 
          method.  Same for the :py:func:`IFile.write`  method it except when
          the :py:func:`IFile.access_mode`  is :py:attr:`FileAccessMode.append_only` 
          or :py:attr:`FileAccessMode.append_read` .
  
          in offset of type int
              Offset to seek relative to the position specified by @a whence.
  
          in whence of type :class:`FileSeekOrigin`
              One of the :py:class:`FileSeekOrigin`  seek starting points.
  
          return new_offset of type int
              The new file offset after the seek operation.
