Move the summary jslib in a dedicated repo

[oleiade]

It has been decided internally to not hold any actual jslib code in the repository itself anymore. As a result, we should move the summary jslib into a dedicated repository. As a matter of fact, a repository already exists but is not used by the jslib repository.

Thus we should go through the necessary steps to include the summary jslib from its dedicated repo as follows:

1. add a build system to the k6-jslib-summary repo able to produce build files
2. create a build and release for its latest version
3. include this version and its build files in the jslib repo
4. remove the actual summary code present in the repo

👍 Another step here is to release another version of the summary library (v0.0.2? v0.1.0? v1.0.0 - not sure) with the slightly newer code that lives in the k6 repo: https://github.com/grafana/k6/blob/master/js/summary.js
