The Mach-O parser accepts invalid library ordinals while traversing the exports trie about lief

Following the reply in #994, it follows the same logic:
LIEF does not aim at following the same logic as the loader. It should cover
all the cases that are supported by the different loaders, but if it covers more,
it should not be a big deal.

In this case, if you need to enforce some checks for your use case, you can add
an additional check on the unicode status of the symbols.

Thanks for the detailed answer. Indeed, I would have expected the LIEF parser to comply with the "specification". From my point of view, the parsing just ends up being lost in random bytes and the reported data does not make much sense as the original bytes did not either.

However, I understand your design choices and can stand by them. If your decision is final, then this issue can be closed and I'll try to add some additional checks on my end.
