* Open an image.
* Try the created image decoder one by one. Once one is able to open the image that decoder is save in `dsc`
* @param dsc describe a decoding session. Simply a pointer to an `lv_img_decoder_dsc_t` variable.
* @param src the image source. Can be
* 1) File name: E.g. "S:folder/img1.png" (The drivers needs to registered via `lv_fs_add_drv()`)
* 2) Variable: Pointer to an `lv_img_dsc_t` variable
* 3) Symbol: E.g. `LV_SYMBOL_OK`
* @param color The color of the image with `LV_IMG_CF_ALPHA_...`
* @return LV_RES_OK: opened the image. `dsc->img_data` and `dsc->header` are set.
* LV_RES_INV: none of the registered image decoders were able to open the image.
