Monorepo: Update readme, setup typescript, setup jest

[FrederickEngelhardt]

Lerna setup

• swap to lerna hoist option speed things up
• clean up package version discrepancies
• add update and update checking scripts for all lerna dependencies
• add cleanup scripts for package-lock.json spawning to maintain latest versions each time we run lerna bootstrap.
• add readme update regarding lerna installlation and what hoisting does.

Typescript setup

• add monorepo compilation for JS and TS files for all packages
• add initial typings for particle-cli package
• use CommonJS as target
• hybrid cjs and esm app research (see below)
• json import refactor to pull in package.json for npm link in dist/package-name*

ESM & CJS targets for typescript

Did some research on commonjs and esm hybrid module support. This provides an option for modern browsers to use the ESM.

Doing so will make the testing and compilation a bit more complex. Example you have two targets, so you now have to create two different scripts for compilation and for testing.

Jest setup

• add support for typescript
• add support for normal js tests
• example code to particle-cli package
