// Workaround - bug in cam library - enable bits are set without using bitwise OR logic -> only latest enable setting is used
// Reference: https://esp32.com/viewtopic.php?f=19&t=14376#p93178
/* The memory structure is as follows for
byte_0 = enable_bits
byte_0->bit0 = enable saturation and hue --> OK
byte_0->bit1 = enable saturation --> OK
byte_0->bit2 = enable brightness and contrast --> OK
byte_0->bit3 = enable green -> blue spitial effect (Antique and blunish and greenish and reddish and b&w) enable
byte_0->bit4 = anable gray -> red spitial effect (Antique and blunish and greenish and reddish and b&w) enable
byte_0->bit5 = remove (UV) in YUV color system
byte_0->bit6 = enable negative
byte_0->bit7 = remove (Y) in YUV color system
byte_1 = saturation1 0-255 --> ?
byte_2 = hue 0-255 --> OK
byte_3 = saturation2 0-255 --> OK
byte_4 = reenter saturation2 in documents --> ?
byte_5 = spital effect green -> blue 0-255 --> ?
byte_6 = spital effect gray -> red 0-255 --> ?
byte_7 = contrast lower byte 0-255 --> OK
byte_8 = contrast higher byte 0-255 --> OK
byte_9 = brightness 0-255 --> OK
byte_10 = if byte_10==4 contrast effective --> ?
