#define HAS_SPI_FLASH_COMPRESSION 1
/**
* This class manages and optimizes SPI Flash data storage,
* keeping an internal buffer to write and save full SPI flash
* pages as needed.
*
* Since the data is always in the buffer, the class is also
* able to support fast on-the-fly RLE compression/decompression.
*
* In testing with the current LVGL_UI it compacts 2.9MB of icons
* (which have lots of runs) down to 370kB!!! As a result the UI
* refresh rate becomes faster and now all LVGL UI can fit into a
* tiny 2MB SPI Flash, such as the Chitu Board.
*
* == Usage ==
*
* Writing:
*
* The class keeps an internal buffer that caches data until it
* fits into a full SPI Flash page. Each time the buffer fills up
* the page is saved to SPI Flash. Sequential writes are optimal.
*
* SPIFlashStorage.beginWrite(myStartAddress);
* while (there is data to write)
* SPIFlashStorage.addData(myBuffer, bufferSize);
* SPIFlashStorage.endWrite(); // Flush remaining buffer data
*
* Reading:
*
* When reading, it loads a full page from SPI Flash at once and
* keeps it in a private SRAM buffer. Data is loaded as needed to
* fullfill requests. Sequential reads are optimal.
*
* SPIFlashStorage.beginRead(myStartAddress);
* while (there is data to read)
* SPIFlashStorage.readData(myBuffer, bufferSize);
*
* Compression:
*
* The biggest advantage of this class is the RLE compression.
* With compression activated a second buffer holds the compressed
* data, so when writing data, as this buffer becomes full it is
* flushed to SPI Flash.
*
* The same goes for reading: A compressed page is read from SPI
* flash, and the data is uncompressed as needed to provide the
* requested amount of data.
