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.

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

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.
