Subject: [PATCH 16/17] new(mock-data, demo): add stable randomness (#1033)

* deps(mock-data): d3-random@^2.2.2 for seeded random

* new(mock-data): add getSeededRandom, support seeds in all generators

* test(mock-data): add tests for seeded random across generators

* new(mock-data): export getRandomNormal

* internal(demo): use stable randomness for all demos
