If adding is done without check it can trigger OOM when fuzzing.

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.

This at least continues processing, so other properties are processed properly.

0dea4a301c Bug 66425: Avoid exceptions found via poi-fuzz 
Processing formats uses regular expressions. Very complex formats
can recurse very deeply and thus can cause StackOVerflows depending
on the used stack-size.

In order to handle this a bit more gracefully, we now catch this
and report a better exception with details about the parsed 
format and potential mitigation.

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.
