[rtextures] Rotated JPG images do not load rotated

[TobinCavanaugh]

• I tested it on latest raylib version from master branch
• I checked there is no similar issue already reported
• I checked the documentation on the wiki
• My code has no errors or misuse of raylib

Issue description

Textures in the jpg format do not maintain their rotated state when loaded by Raylib. PNGs work fine, but when a jpg that has been rotated, it gets loaded as its unrotated version.

(see Issue Screenshot)

This seems to be an issue with the loading of the jpg metadata.

Environment

Windows 10 Pro, Intel Iris Xe Graphics, GL_VERSION: 3.3.0 - Build 32.0.101.5972

Code Example

#include "raylib.h"

#define SCREEN_WIDTH (800)
#define SCREEN_HEIGHT (450)

#define WINDOW_TITLE "Window title"

int main(void) {
    InitWindow(SCREEN_WIDTH, SCREEN_HEIGHT, WINDOW_TITLE);
    SetTargetFPS(60);

    Texture2D reg = LoadTexture(ASSETS_PATH"regular.jpg");
    Texture2D rot = LoadTexture(ASSETS_PATH"rotated.jpg");

    while (!WindowShouldClose()) {
        BeginDrawing();
        ClearBackground(BLACK);

        DrawTexture(reg, 0, 0, WHITE);
        DrawTexture(rot, 0, reg.height, WHITE);

        DrawFPS(0, 0);
        EndDrawing();
    }

    CloseWindow();

    return 0;
}

regular.jpg and rotated.jpg

stb_image doesn't seem to be making any attempt to parse/load any metadata, so raylib can't either.
Probably best to do that yourself. If this one instance of the metadata is implemented, there's also a question of what other metadata is unsupported that could confuse users.

@TobinCavanaugh I'm afraid raylib does not support loading metadata from images, actually, afaik, stb_image neither supports that option. In any case, supporting it would be out of scope for raylib, it seems a very specific use case need.
