More colors for LED color control

[alve89]

In addition to the existing LED color control I'd like to share more available colors on newer models (I'm using a R503 module). Maybe this is helpful for others, so just add the following lines after #define FINGERPRINT_LED_GRADUAL_OFF 0x06 //!< Gradually off in Adafruit_Fingerprint.h:

#define FINGERPRINT_LED_WARMWHITE 0x00  //!< warm white
#define FINGERPRINT_LED_GREEN 0x04  //!< green
#define FINGERPRINT_LED_YELLOW 0x05  //!< yellow
#define FINGERPRINT_LED_CYAN 0x06  //< cyan
#define FINGERPRINT_LED_ COLDWHITE 0x07  //< cold white

And as "issue": In line 89 of Adafruit_Fingerprint.h stands //!< Purple LEDpassword which is obviously wrong, so please just remove the password.

Have a nice day all together!

How was 0x00 for warm white determined?

This also may not be available on all models depending on what firmware they are running:

fixing last line in:
#define FINGERPRINT_LED_WARMWHITE 0x00 //!< warm white
#define FINGERPRINT_LED_GREEN 0x04 //!< green
#define FINGERPRINT_LED_YELLOW 0x05 //!< yellow
#define FINGERPRINT_LED_CYAN 0x06 //< cyan
#define FINGERPRINT_LED_ COLDWHITE 0x07 //< cold white
by removing an extra space, so it becomes:
#define FINGERPRINT_LED_COLDWHITE 0x07 //< cold white
