Build flashblocks until timeout and choose the best one #190
Description
Right now we are building flashblocks and sleeping until it's time to send it (if there is time left after we are done)
We want to have following behavior:
Build flashblock, if there is time left before this flashblocks deadline (usually 250ms, configurable) start building flashblock again and choose the best between 2. Continue this process until we reach deadline.
This would allow us to include transaction that arrived during current flashblock build process
