Dave Allie a268aaf6e2 Skip pagebreak blocks when parsing epub file (#58) 
## Summary

* Skip pagebreak blocks when parsing epub file
* These blocks break the flow and often contain the page number in them
which should not interrupt the flow of the content

Dave Allie 85c1db7c5c Fix font readability by expanding blacks and trimming whites (#55) 
## Summary

* Previously, only pure black pixels in the font were marked as black,
this expands the black range, and makes the lightest pixels white

## Additional Context

* Noticed personally it was kind of "thin" and washed out a bit, this
massively helps, should also address concerns raised here:

Dave Allie ee63cf4f18 Rename Screens to Activities and restructure files (#44) 
## Summary

* This PR drastically reshapes the structure of the codebase, moving
from the concept of "Screens" to "Activities", restructing the files and
setting up the concept of subactivities.
* This should help with keep the main file clean and containing all
functional logic in the relevant activity.
* CrossPointState is now also a global singleton which should help with
accessing it from within activities.

## Additional Context

* This is probably going to be a bit disruptive for people with open
PRs, sorry 😞

Dave Allie 6879efac82 Use 6x8kB chunks instead of 1x48kB chunk for secondary display buffer (#36) 
## Summary

- When allocating the `bwBuffer` required to restore the RED RAM in the
EPD, we were previously allocating the whole frame buffer in one
contiguous memory chunk (48kB)
- Depending on the state of memory fragmentation at the time of this
call, it may not be possible to allocate all that memory
- Instead, we now allocate 6 blocks of 8kB instead of the full 48kB,
this should mean the display updates are more resilient to different
memory conditions

Dave Allie eec3766bcf Use single buffer mode for EInkDisplay (#34)
