## Summary
* Rely on media-type="application/x-dtbncx+xml" to find TOC instead of
hardcoded values
## Additional Context
* Most of my epubs don't have id==ncx for toc file location. I think
this media-type is EPUB standard

## 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
## Additional Context
* add horizontal indent in first line of paragraph in case Extra Paragraph Spacing is OFF
* Treat tabs as whitespace (so they are properly stripped)
* Changed size of indent to 1 em.
* Fixed calculation of space when indenting (avoiding squeezed text).
* Source code formatting
* Enhance TOC parsing and chapter selection logic
- Update .gitignore to include additional paths
- Refactor Epub::parseContentOpf to improve NCX item retrieval
- Modify ContentOpfParser to store media type in ManifestItem
- Implement rebuildVisibleSpineIndices in EpubReaderChapterSelectionScreen for better chapter navigation
- Adjust rendering logic to handle empty chapter lists gracefully
* Refactor TOC parsing logic to streamline cover image and NCX item retrieval
* add cyrillic ranges
* revert
* clang format fix
* white sleep screen
* quicker pwr button
* no extra spacing between paragraphs
* Added settings class with de/serialization and whiteSleepScreen setting to control inverting the sleep screen
* Added Settings screen for real, made settings a global singleton
* Added setting for extra paragraph spacing.
* fixed typo
* Rework after feedback
* Fixed type from bool to uint8
* First pass at moving to SDK EInkDisplay library
* Add 2-bit grayscale text and anti-aliased rendering of text
* Render status bar for empty chapters
* Refresh screen every 15 pages to avoid ghosting
* Simplify boot and sleep screens
* Give FileSelectionScreen task more stack memory
* Move text around slightly on Boot and Sleep screens
* Re-use existing buffer and write to whole screen for 'partial update'
* Add expat and swap out ERB HTML parser
* Increase EpubHtmlParserSlim file buffer to 1024 bytes
* Cleanup TextBlock functions
* Do not break words when leaving spans
