### LCD Bridge
The LCD bridge will be able to bridge any device class implementing `LcdDeviceInterface`
to stdin or a named pipe. This basically creates a user-space daemon to interface with
the display without having to fiddle with bits.

Commands should include:
* `CLR` - clears the display (`LcdDeviceInterface#clear()`)
* `LOC n m` - moves the cursor to line n column m (0-indexed) (`LcdDeviceInterface#setCursorPos(n,m)`)
* `FONT n` - loads the default font (0) or a custom font file (`LcdDeviceInterface#setFont()`)
* `OUT s` - Write text to the display (`LcdDeviceInterface#write()`)
* `MODE s` - Set text modes (`LcdDeviceInterface#setTextMode()`)
#### Modes
As supported:
* `+R`/`-R` - Set/clear inverse
* `+B`/`-B` - Set/clear bold
#### Fonts
#### Location and write
Location is maintained and incremented after writes.
