80fd35198d Bug 66425: Avoid exceptions found via poi-fuzz 
Prevent too deep nesting by throwing an exception
instead of just not parsing more nesting-levels as
this still caused OOMs.

Allow to adjust the limit via static setter as elsewhere
to give users a chance to parse very complicated files
if really necessary.

107def2e65 Bug 66425: Avoid a StackOverflowException found via oss-fuzz 
We try to avoid causing StackOverflow, but it was possible
to trigger one here with a specially crafted input-file.

This puts a limit on the number of nested children in place
and logs a warning when the Stream is not fully parsed.

Should fix https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=61256
