[C++] Investigate recursive data types limit in flatbuffers

[asfimport]

This was discovered when testing out recursion limit code. It appears there is a bug in our code or a limitation in flatbuffers that a nested type of length ~71 doesn't round trip correctly.

[~emkornfield@gmail.com] do you have a unit test to reproduce this?
Is it a problem? 71 levels of nesting sounds like a lot.

Micah Kornfield / @emkornfield:
I don't think its a blocker it is a lot. It was just surprising (and a strange number to break at). I discovered it while writing https://github.com/apache/arrow/blob/master/cpp/src/arrow/ipc/ipc-adapter-test.cc#L221
