Update s2 to use published version from npm

Since I got pinged here, I might as well update it.

Sorry, it's no longer keyed:

npm run isKeyed -- --headless true keyed/s2
Keyed test for create rows failed. Expected that 1000 TRs should be removed and added, but there were 0 added TRs and 0 were removed
s2-v1.0.17-keyed is non-keyed for 'run benchmark' and keyed for 'remove row benchmark' and keyed for 'swap rows benchmark' . It'll appear as non-keyed in the results
ERROR: Framework s2-v1.0.17-keyed is not correctly categorized

We can either move it to non-keyed or you'd have to fix the behavior.

huh... I'll fix that

the keyed test has been satisfied, i did have to add a line in the implementation to force the keyed behavior.
