09fbfd5be4 Bug 66425: Avoid exceptions found via poi-fuzz
Avoid a possible OutOfMemoryException with many child-records

This avoids having too many children in EscherRecords, the limit of
100_000 is arbitrarily chosen and can be adjusted if needed  

Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=62924 and maybe others

2582e5e0c1 Bug 66425: Avoid exceptions found via poi-fuzz
Avoid a possible StackOverflowException

This adds support of counting of the "nesting level" into the base 
EscherRecord and thus makes this existing limitation much more effective
as it kicks in for more types of nested records.

1b7613329e Bug 66425: Add memory-safeguard in one more place
We try to generally avoid overly large allocations in places
where arrays are allocated. 

We add one more such check for pictures in HSLF.

We might need to increase the used value of 10MB if users report 
larger files being used frequently. 

Overriding this check via IOUtils is possible.

d1c9a07860 Add the ability to edit HSLFPictureData contents
Pictures can now be edited by calling HSLFPictureData#setData(byte[]). The byte[] should contain the image data as an image viewer might read it.

To enable this functionality, a tighter coupling between the EscherBSERecords of the slideshow and the HSLFPictureData was required. This ensures that changes in image data size are accurately recorded in the records.

In the course of coupling the records and the HSLFPictureData, various scenarios arose where a mapping of records to pictures was non-trivial. Accordingly, the HSLFSlideShowImpl#matchPicturesAndRecords(...) function was added to perform a more sophisticated matching pass. This function is heavily exercised by org.apache.poi.hslf.usermodel.TestBugs.testFile[5] and PPTX2PNG.render[2], as well as the new TestPictures#testSlideshowWithIncorrectOffsets().

Closes #225
