Branch ehp/GH-11-eslint-config has the updates. Removed old packaged. Created new eslint and prettier config. Fixed one file src/eosjs-jsonrpc.ts. Package upgrades to eslint, typedoc, typescript, and node. Added eslint-config-prettier, eslint-plugin-es-x, eslint-plugin-prettier.

ToDo: Need to test and eslint --fix src/ all the other files as well.
ToDo: Regenerate documentation and make sure they work
ToDo: Rerun tests to make sure changes didn't break anything
