The ReferencePillar should be able to handle FilePart for very large files

Has the following comment:
This is fine for smaller files and smaller offsets, but it might have issues for large files (limit of int).
If the offset or the length of the filepart is large than what can be defined by an int, then issues will arrise.
In such a case, the file part should be written to a separate file, which is then uploaded (and afterwards deleted).
