Option Flows are now being parsed. Sampling and Database support upcoming!

how much different is it to parse v10 vs parsing v9?

Sorry for the delay, i was on travel.

It is technically the same, with some minor differences - you can't just copy the impl. tried that. failed.

On another note, i rewrote this whole thing in golang, to be put into this repo quite soon. This will be archived.
