Adds Mouse Support

[ivanvanderbyl]

Implements #45

Usage

// perform a click at 100 by 120 pixels from top left corner
await browser.mouse.click(100, 120)

// Perform a drag from 100,100 to 200,200
await browser.mouse.drag(
  [100, 100],
  [200, 200],
)

// primitive mouse down
await browser.mouse.down()

// primitive mouse move
await browser.mouse.move([x1,y2], [x2,y2],[xn,yn])

// primitive mouse up
await browser.mouse.up()

Supports most of the same options as Puppeteer.

Other things to note:

• Upgrades Puppeteer to 1.17

TODO:

• Docs
• Tests - needs a page to test actual events.

@ivanvanderbyl if this has been created, we should update https://wilsonmar.github.io/flood-the-internet/#challenges-on-the-internet-app, which has a page to test actual events.
