Backwards compatibility warning: The result will from now on omit empty fields instead of including a zero value (e.g. no more `balance: '0x'`). The prestateTracer will now take an option `diffMode: bool`. In this mode the tracer will output the pre state and post data for the modified parts of state. Read-only accesses will be completely omitted. Creations (be it account or slot) will be signified by omission in the `pre` list and inclusion in `post`. Whereas deletion (be it account or slot) will be signified by inclusion in `pre` and omission in `post` list. Signed-off-by: Delweng <delweng@gmail.com>
