@cchantep I think the existing tests do a good job of testing this code change. |

Alternative to #1073
This change avoids creating NumericNodes and parsing strings to numbers which ultimately have to be turned back to strings to write them.
I've had to leave the BigIntegerNode usage in there. Removing it breaks some tests. I've debugged and it is down to how writeNumber(String) is implemented in jackson-databind TokenBuffer. We would need to change this class in jackson-databind to fix this (and that is not likely to happen as it will probably cause other issues). Basically, writeNumber(String) is assumed to be a non-integer in TokenBuffer.
