FR: Include Atkinson Hyperlegible as a default bundled font

[Atrate]

Does your feature request involve difficulty completing a task? Please describe.
A person with vision deficiency has recommended this (open) font to me: https://www.brailleinstitute.org/freefont/ I think that it would be nice to have such a font installed as a default font bundled with KOReader, as it would (hopefully) help other vision-deficient users.

Describe the solution you'd like
Bundle Atkinson Hyperlegible with KOReader.

Describe alternatives you've considered
Installing the font manually. That works, but I think that habving it available by default would be nice.
