add init

[eteq]

This is about as trivial as a PR comes (adding a blank file...), but it seemed to me this was necessary to get python setup.py install to work correctly to let this by useable on blinka/non-cirtcuitpython?

On a raspberry pi 3B+ I was able to install this library successfully with these commands

pip3 install adafruit-circuitpython-display-text

These also were working successfully for me:

git clone https://github.com/adafruit/Adafruit_CircuitPython_Display_Text.git
cd Adafruit_CircuitPython_Display_Text
sudo python3 setup.py install

In both cases I tested the install with a Blinka Displayio simpletest script for ili9341 screen.

Even though it does seem to be working for me as-is, I do think we probably want to include an __init__.py file like you've added so that it can be a proper python package.

Looking over at this library as an example: https://github.com/adafruit/Adafruit_CircuitPython_MCP230xx/blob/master/adafruit_mcp230xx/__init__.py

I see that the empty init file does include a few license lines.

Can you add these to the file you created and make a new push please?

I don't think we need a license for an empty file. Nothing to license. :-)

Seems good to me now then. I did a quick test with the anchor point example with both label and bitmap_label and had no issues.

Thank you @eteq
