Book cover sleep screen (#89)
## Summary

* Fix issue with 2-bit bmp rendering
* Add support generate book cover BMP from JPG and use as sleep screen

## Additional Context

* It does not support other image formats beyond JPG at this point
* Something is cooked with my JpegToBmpConverter logic, it generates
weird interlaced looking images for some JPGs

This directory is intended for project specific (private) libraries.
PlatformIO will compile them to static libraries and link into the executable file.

The source code of each library should be placed in a separate directory
("lib/your_library_name/[Code]").

For example, see the structure of the following example libraries `Foo` and `Bar`:

|--lib
|  |
|  |--Bar
|  |  |--docs
|  |  |--examples
|  |  |--src
|  |     |- Bar.c
|  |     |- Bar.h
|  |  |- library.json (optional. for custom build options, etc) https://docs.platformio.org/page/librarymanager/config.html
|  |
|  |--Foo
|  |  |- Foo.c
|  |  |- Foo.h
|  |
|  |- README --> THIS FILE
|
|- platformio.ini
|--src
   |- main.c

Example contents of `src/main.c` using Foo and Bar:
```
#include <Foo.h>
#include <Bar.h>

int main (void)
{
  ...
}

```

The PlatformIO Library Dependency Finder will find automatically dependent
libraries by scanning project source files.
