i2c lib doesn't work w/ latest node

[NateZimmer]

Hey man,

Awesome lib, your performance update would be sweet to use. Unfortunately your lib uses i2c instead of i2c-bus so it no longer works w/ node >9.11 to my knowledge. E.g.

var oled = new oled(opts);
TypeError: domain.enter is not a function

This was later solved in yet another nother fork https://github.com/baltazorr/oled-i2c-bus but i'm guessing they don't have your performance enhancement.

Going to try to give this lib some TLC and see if I can merge your stuff w/ the latest fork
