Memory leak fix and camera multithreading safety improvement (#239)

Browse Source 
* memory leak fix and attempt at optimizing space

* camera rework

try to use better locking algorithm (MRSW lock on wikipedia)

* add time print (toggleable) and stuff

remove old mixed qr thingss from main

* remove the dumb 3 bytes saving

* remove useless time measure code

* forgot to close the stop event handle

* fix memory leak when loading icon from smdh

* fix entry path on folders

optimization using memcpy cause it to have the "/info.smdh" when the entry is a folder. simply remove that with a memset to 0.
