📄 Description

Hi, in order to save memory I tried to make the python heap resizable. Here is how it works :

after a reset you can go in the settings to modify the size from 16kbi to 62kBi, even if there are some crashs with 16kbi you can save until 51kbi. The crashs are just with the code app not the whole calculator.
then if you go in the code app you will have less memory available for it because it will be used by others apps, files, ...
to use the free memory you can use two pointers which give you the address : char *memory_heap_available_start;
&& char *memory_heap_available_end; in the GlobalPreferences.
I noticed a problem (a graphical one) in the python sub menu in the settings, I can only print 4 cells so I removed the cursor saving switch (but it is actually here in the code) in order to test/use my new cell.
I hope it will be usefull :p
