Minor issue in the wiki

[Chris Salch]

https://github.com/tabemann/zeptoforth/wiki/Bitmaps,-Fonts,-and-I2C-SSD1306-based-Displays-for-zeptoforth#hello-world

The code listed to write "Hello World!" uses set-string instead of draw-string. In particular the line that looks like:

s" Hello, World!" my-width 2 / 7 13 * 2 / - my-height 2 / 8 2 / - my-ssd1306 a-simple-font set-string

should instead look something like:

s" Hello, World!" my-width 2 / 7 13 * 2 / - my-height 2 / 8 2 / - op-set my-ssd1306 a-simple-font draw-string

I'm not overly familiar with github wiki's or I'd offer a more direct fix ..

Thanks for the heads-up! I have now fixed the example as you mention and tested it.

Looks good to me! That confused the heck out of me until I realized set-string wasn’t defined and went spelunking through git history.
