M5ez 2.1.0 released

[Rop]

Hi all,

Sorry to have been away from this for a bit... I just released M5ez version 2.1.0, with the following fixes:

• Canvas scrolling off by default
• Fixed off by one in wifi network handling (#32)
• Added ez.clock.waitForSync()
• Move wire.begin so it doesn't get run when FACES is off

Note that if your code uses scrolling on the canvas, you have to turn that on first using ez.canvas.scroll(true).
