Fixed sharing SPI data lines and fill logic

Fixed Issues #21 and #22 . The prior version did not release EPD SRAM CS_pin between updates. As a result, sharing the SPI lines with another device would cause miscommunication. Also, within the EPD board, there was miscommunication which caused the fill logic to fail. Both problem were fixed with this change.

Fix for CircuitPython 4.0.0 RC2 and later

There was an issue with CircuitPython 4.0.0 RC2 and later where byte checking was removed that caused the EPD library to fail. This fix allows the library to be used with the latest version of CircuitPython. Thanks @mrmcwethy
