Fixes for MP support for LVGL 3rd party libraries
337076f 
Add missing lv_qrcode_class

Remove 'struct JDEC' from public API. This struct is needed intenally on tjpgd.c and lv_sjpg.c, but doesn't need to be exposed in the public API. When exposed, it increases Micropython binding program size and some fields are not supported today (uint8_t* huffbits[2][2]). To overcome this, moved it to a new H file which is not included in public API, only in sjpg C files

* lv_qrcode: add lv_class_qrcode

Must define a distinct class for every widget, to allow Micropython bindings convert lv_obj_t into the specific class

* gifdec.c: fix uninitialized

ESP32 reports some potentially uninitialized variables. Initialize them to prevent the errors

* src/extra/libs/sjpg: smaller public header

Only keep lv_split_jpeg_init in public header, since JPEG is used with image decoder

* Remove tjdec.h
