Noticed that the Indexing... popup went missing despite 3-5 seconds
delay. Reducing to 10KB, so we get a popup for delays > ~2s.

## Summary
Use non-crop mode as expected for home thumb generation. I likely broke
this when I fixed the artifacts on the sleep screen.

## Summary
* Adds a menu in the Epub reader
* The Chapter selection is moved there to pos 1 (so it can be reached by
double tapping the confirm button)
* A Go Home is there, too
* Most significantly, a function "Delete Book Cache" is added. This
returns to main (to avoid directly rebuilding cached items, eg. if this
is used to debug/develop other areas - and it's also easier ;))
Probably, the Sync function could now be moved from the Chapter
selection to this menu, too.

Let's start small by showing the ALT text of IMG. This is rudimentary,
but avoids those otherwise completely blank chapters.
I feel we will need this even when we can render images if that
rendering takes >1s - I would then prefer rendering optional and showing
the ALT text first.
## Summary
Adds define to omit optional fonts from the build. This reduces time to
flash from >31s to <13s. Useful for development that doesn't require
fonts. Addresses #193
Invoke it like this during development:
`PLATFORMIO_BUILD_FLAGS="-D OMIT_FONTS" pio run --target upload && pio
device monitor`
Changing the define causes `pio` to do a full rebuild (but it will be
quick if you keep the define).

## Summary
Skip BOM character (sometimes used in front of em-dashes) - they are not
part of the glyph set and would render `?` otherwise.

1. Refactor Bitmap.cpp/h to expose the options for FloydSteinberg and
brightness/gamma correction at runtime
2. Fine-tune the thresholds for Floyd Steiberg and simple quantization
to better match the display's colors
Turns out that 2 is enough to make the images render properly, so the
brightness boost and gamma adjustment doesn't seem necessary currently
(at least for my test image).
Added a setting to select `fit` or `crop` for cover image on sleep
screen.
Might add a `expand` feature in the future that does not crop but rather
fills the blank space with a mirror of the image.

This parses the guide section in the content.opf for text/start
references and jumps to this on first open of the book.
Currently, this behavior will be repeated in case the reader manually
jumps to Chapter 0 and then re-opens the book. IMO, this is an
acceptable edge case (for which I couldn't see a good fix other than to
drag a "first open" boolean around).

Improves the duration for which the power button needs to be held - see
#53.
I left the measurement code for the calibration value in, as it will
likely change if we move the settings to NVS.
Still a bit raw, but gets the time required to determine the size of
each chapter (for reading progress) down from ~25ms to 0-1ms.
This is done by keeping the zipArchive open (so simple ;)).
Probably we don't need to cache the spine sizes anymore then...

Adresses #53
Please check if we still need the code to "Give the user up to 1000ms to
start holding the power button, and must hold for
SETTINGS.getPowerButtonDuration()" - the power button should be pressed
already when waking up...
Also, decided to return before the delay to wait more to make the
behavior more immediate.
