Describe the bug

Since the recent update of Saber v0.25.2 it is possible to open large pdf files of over a hundred pages. When I start annotating the first 10 of a 60 pages long pdf file, the size growths from 1.8 MB to over 70 MB. I measure this size by exporting the note as .sba file.

To reproduce

1. Import a large pdf file
2. Start annotating the document
3. Export this document
4. See large file size

Expected behavior

It should only be an increase by a few megabyte, when I annotate the first 10 pages on a pdf

Saber version

v0.25.2
