Add protection against unlimited nesting of object encodings

[locka99]

Arrays may contain Arrays may contains Arrays.... or other variations of data nested in other data. Decoding provide a nesting context and a nesting limit on each decode operation to allow the decoder to abort the decoder if it goes too deep.

Requires some unit tests for the same if possible.

Most probably the existing decoding limits may have to be modified to decoding state, or there is some other similar mechanism
