Check if we can make the display code faster

[tuxBurner]

The display code is really slow and already token to an own sub node js process so it will not block the main loop.

Perhaps we should also take a look at noopkat/oled-js#114
Also we should check if the i2c or spi modules have speed diffrents

The main issue is that you send the data byte by byte, heres a commit in my fork of a fork that made the library MUCH faster. Now it performs similar to the C library I used before.
