Graceful max header size logic

[cadorn]

• [ ] Add maxHeaderSize option
• [ ] If size of reached stop sending more log messages
• [ ] If traversing an object and getting close to limit, do not traverse as deep in hope of keeping room for more log messages
• [ ] Object trim capability where objects can be encoded and then trimmed to a certain size to keep room for more log messages
• [ ] Keep track of encoded object sizes and associated classes and rank classes by size to assist in adding object filters
• [ ] Option to blacklist all classes and only show stub of first hidden object and ability to whitelist classes to traverse them.
