Fix reporter and mock types

[lieutdan13]

I discovered an issue where the types on the ExercisedInteraction interface didn't match the Interaction interface it extends. See the issue below when running tsc. I've resolved this by creating a few super class interfaces with more broad types, but the child classes have more defined types.

  Types of property 'calls' are incompatible.

In addition to fixing the types, I've also added eslint and typescript related packages to the dev dependencies to support the npm run lint and the new npm run build scripts.
