Correct #263, add setup file for 160x80 TFT, add invert option

Fixed bug where wrong wodth was returned for 1bpp Sprite
Improved speed for copying a 1bpp Sprite into another 1bpp Sprite (
affects Sprite pushImage() function only)
Added option to setup for colour inversion

+// We must use hardware SPI, a minimum of 3 GPIO pins is needed.
+// Typical setup for ESP8266 NodeMCU ESP-12 is :
+//
+// Display SDO/MISO  to NodeMCU pin D6 (or leave disconnected if not reading TFT)
+// Display LED       to NodeMCU pin VIN (or 5V, see below)
+// Display SCK       to NodeMCU pin D5
+// Display SDI/MOSI  to NodeMCU pin D7
+// Display DC (RS/AO)to NodeMCU pin D3
+// Display RESET     to NodeMCU pin D4 (or RST, see below)
+// Display CS        to NodeMCU pin D8 (or GND, see below)
+// Display GND       to NodeMCU pin GND (0V)
+// Display VCC       to NodeMCU 5V or 3.3V
+//
+// The TFT RESET pin can be connected to the NodeMCU RST pin or 3.3V to free up a control pin
+//
+// The DC (Data Command) pin may be labeled AO or RS (Register Select)
+//
+// With some displays such as the ILI9341 the TFT CS pin can be connected to GND if no more
+// SPI devices (e.g. an SD Card) are connected, in this case comment out the #define TFT_CS
+// line below so it is NOT defined. Other displays such at the ST7735 require the TFT CS pin
+// to be toggled during setup, so in these cases the TFT_CS line must be defined and connected.
+//
+// The NodeMCU D0 pin can be used for RST
+//
+// See Section 2. below if DC or CS is connected to D0
+//
+// Note: only some versions of the NodeMCU provide the USB 5V on the VIN pin
