Update diff.rb

[tkstanczak]

add a list of signers and their last signed blocks to the block data (like Clique snapshot)

that's a good find. my "conditions" are just the precondition for getting stuck. 👍

with 20% network fragmentation, I get:

2019-07-09 13:40:14 [SIML] Network is stuck... Exciting.

The logs do not indicate why it's stuck, which client is in turn now and why does this situation not allow for a reorg? 84101 and 84100 should clearly allow clients to reorganize.
