Enhance the Readme

[krambono]

Hello,

First of all, I would like to thank you for that program ! It seems good.

For the installation, I had a few problems. I think you should add this to your README :

• python-tk dependency : apt install python-tk python3-tk
• install the program with these commands :

  python3 setup.py build
  python3 setup.py install

I am on mac and I am getting OSError: cannot open resource when trying to run flowkey-dl. It seems to have to do with the fonts fnt = [ImageFont.truetype('FreeMono.ttf', sz) for sz in font_size]. Do you know how to fix this? I didn't run apt install python-tk python3-tk because I believe Tkinter should already be installed with python on mac.

As far as I know, tkinter should be included in python by default. However, I added the note as you suggested. Did the installation using pip fail?

The font issue is separate, but I added additional workarounds: if freemono is not found, I now try to load arial, and if that is not there the default is loaded - which is fixed size but better than crashing the app. The fix would be to install the corresponding font on your system, such that ImageFont finds it. See https://pillow.readthedocs.io/en/stable/reference/ImageFont.html

Your fix worked, thanks @MatthiasLienhard!

@MatthiasLienhard Actually when trying to save a sheet I get this error:

Seems like it is related to the Tkinter changes you might've made?

You have to create the "raw" directory. /Users/SGGS1234/opt/anaconda3/lib/python3.8/site-packages/flowkey_dl/raw/ @MatthiasLienhard I was talking about this in my other issue.

I assume all for all separate issues there is at least a workaround
