Graphology upgrade report

[Yomguithereal]

@jacomyal @sim51 I just upgraded graphology to 0.22.1 in the repo. It does not affect anything apart from package.json files as it seems. The upgrade is only mostly breaking if you used the #.forEach*Until methods and advanced #.degree trickery so most projects should be fine.

Some remarks:

1. I did not upgrade the demo because react-sigma-v2 has a peer dep which does not allow 0.22.1.
2. better-edge-measures seem to be mergeable without issues at this point.

Check f46a567 for reference.

It would be good if someone other than me could peruse the v0.22 changelog and assert whether I missed something obvious: https://github.com/graphology/graphology/blob/master/CHANGELOG.md#0220

FYI, I updated today the react lib, mainly for the peer dependencies mapping
