Add SH1107 OLED driver support to usermod_v2_four_line_display_ALT

[Drizzt321]

Is your feature request related to a problem? Please describe.

I have this adafruit 128x64 OLED with buttons, and it uses SH1107 driver, not SSD1306 which is what is currently supported in the [v2 Four Line Display & ALT](https://github.com/atuline/WLED/tree/master/usermods/usermod_v2_four_line_display_ALT] user mod. Trying to dig into the code, looks like if I can find the right constructor I can simply add a new type, and create a U8X8 and it Should Work(tm).

Looks like U8X8_SH1107_64X128_SW_I2C and U8X8_SH1107_64X128_HW_I2C are what I need. Unfortun

Unfortunately I do not have a specimen to test and update code.

@blazoncek I tried editing the usermod_v2_four_line_display_ALT.h

Line 111, adding
SH1107_64 // U8G2_SH1107_64X128_2_HW_I2C

In the switch to create the u8x8, added this to the end before the default:

        case SH1107_64:
        Serial.println("Setting SH1107");
          if (!isHW) u8x8 = (U8X8 *) new U8X8_SH1107_64X128_SW_I2C(ioPin[0], ioPin[1]); // SCL, SDA, reset
          else       u8x8 = (U8X8 *) new U8X8_SH1107_64X128_HW_I2C(U8X8_PIN_NONE, ioPin[0], ioPin[1]); // Pins are Reset, SCL, SDA
          break;

I end up getting that output statement on boot (viewing via USB Serial).

Based on your knowledge of the library, should that work?

I'm using this Adafruit ESP32, in the usermod setup for this, 1st is PIN 23 (clk) and second is 22 (data). Pretty sure those would be the correct pins, right? If it'd help, I can buy and send you one, they aren't all that expensive for me.

Just duplicate lines where SH1106 is replacing with appropriate constructor for SH1107.
