this method does not require a conversion from an array, instead can write directly to the interval map

experimental: use morton code to represent chunks
...
This avoids creating new objects (for vec3 or string) for each chunk, and just returns an int. For now, using 10bits is kind of limiting, and some other way of easily expressing ints longer than 32bits is needed

add setup for voxel size
modeling/meshing needs optimization
switch to using a bitfield instead of queues

try new approach based on interval maps
...
they resolve the problems and the redundancies of interval trees, while giving a serius memory usage benefit (20% of the one used by interval trees in test scene)
test scene is a world made of a cube of sides RENDER_DISTANCE*2 with player at the center

Instead of directly calling IntervalTree. This allows clamping indices to avoid out of bounds when converting to and from an array

The structure is still not perfect and needs revising in some edge cases where unneeded child nodes are left instead of being added in the parent
