Second annotation round

Purpose: measure how reliable the role labels are by having an independent person label a sample and comparing.

1. Read ../ANNOTATION_GUIDELINES.md. Do not open ../data/roles/labels.*, ../results/ or any tool output until you have finished.
2. Open round-2/sample.csv (150 types, in a fixed random order). For each row, follow url to the file at its commit and fill role with one of entry client service domain persistence event config none; add a note when the decision is not obvious.
3. Save the file and run python3 scripts/kappa.py annotation/round-2/sample.csv from the repository root. It prints the agreement, Cohen's kappa and the disagreements.
4. The two annotators discuss the disagreements; corrected labels and the agreement figures go into the next release (see CHANGELOG.md).

The sample is drawn in proportion to each project's labels, by a seeded hash, so it can be regenerated with node build/build.js roles.
