Bodmer 4a52f5e685 Add ability to set ST7735 tab color from sketch 
Use line is form:
tft.init(1);
or:
tft.init(INITR_REDTAB);
// Enumerated the configurations in library are:
#define INITR_GREENTAB
0x0
#define INITR_REDTAB    0x1
#define INITR_BLACKTAB  0x2
#define
INITR_GREENTAB2 0x3 // Use if you get random pixels on two edges of
green tab display
#define INITR_GREENTAB3 0x4 // Use if you get random
pixels on edge(s) of 128x128 screen
#define INITR_GREENTAB128 0x5 // Use
if you only get part of 128x128 screen in rotation 0 & 1
#define INITB
0xB

/*
This sketch reads the user setup information from the processor via the Serial Port
It is a support and diagnostic sketch for the TFT_eSPI library:
https://github.com/Bodmer/TFT_eSPI
The output is essentially a copy of the User_Setep configuration so can be used to
verify the correct settings are being picked up by the compiler.
If support is needed the output can be cut and pasted into an Arduino Forum post and
already includes the formatting [code]...[/code] markups.
