Fixed example code in README.md

Example code now correctly declares a fbgl_t buffer and passes it to
relevant functions, also, fbgl_get_{width,height} are renamed to the
kernel functions fb_get_{width,height} as a library-provided wrapper
is non-existent (and probably unnecessary).

 Here’s a simple program that initializes the framebuffer, clears it to a blue color, and draws a red diagonal line.
 
 ```c
-#include <stdio.h>
 #include "fbgl.h"
+#define FBGL_IMPLEMENTATION
+#include <stdio.h>
+
+int main()
+{
+
+    fbgl_t buffer;
 
-int main() {
     // Initialize the framebuffer
-    if (fbgl_init("/dev/fb0") != 0) {
+    if (fbgl_init("/dev/fb0", &buffer) != 0) {
         fprintf(stderr, "Failed to initialize framebuffer\n");
         return 1;
     }
 
-    printf("Framebuffer size: %dx%d\n", fbgl_get_width(), fbgl_get_height());
+    printf("Framebuffer size: %dx%d\n", fb_get_width(), fb_get_height());
 
     // Clear framebuffer to blue
     fbgl_clear(0x0000FFFF); // Blue color
 
     // Draw a red diagonal line
-    for (int i = 0; i < fbgl_get_width() && i < fbgl_get_height(); i++) {
-        fbgl_put_pixel(i, i, 0xFFFF0000); // Red
+    for (int i = 0; i < fb_get_width() && i < fb_get_height(); i++) {
+        fbgl_put_pixel(i, i, 0xFFFF0000, &buffer); // Red
     }
 
     // Wait for user input before exiting
