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.
Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=66137
