Aleo, Noto Sans, Open Dyslexic fonts (#163)

Browse Source 
## Summary

* Swap out Bookerly font due to licensing issues, replace default font
with Aleo
* I did a bunch of searching around for a nice replacement font, and
this trumped several other like Literata, Merriwether, Vollkorn, etc
* Add Noto Sans, and Open Dyslexic as font options
  * They can be selected in the settings screen
* Add font size options (Small, Medium, Large, Extra Large)
  * Adjustable in settings
* Swap out uses of reader font in headings and replaced with slightly
larger Ubuntu font
* Replaced PixelArial14 font as it was difficult to track down, replace
with Space Grotesk
* Remove auto formatting on generated font files
* Massively speeds up formatting step now that there is a lot more CPP
font source
* Include fonts with their licenses in the repo

## Additional Context

Line compression setting will follow

| Font | Small | Medium | Large | X Large |
| --- | --- | --- | --- | --- |
| Aleo |
