Log Message: 
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. 

Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=66374
