Subject: [PATCH] Fixing build error xdrv_13_display.ino with JPEG_PICTS

On ESP32, with `#define JPEG_PICTS` without the scripter, build fails due to the function `Draw_jpeg` being defined after use. Order swapped to satisfy the compiler.

Change tested to compile without errors, but not being 100% sure of when/how it is supposed to work, no verification of this.
