Arena<T extends NativeType> class

Instead of doing many little allocations, Arena allows you to make one large allocation which can then be sliced. This can improve performance and simplify memory management.

final buffer = Uint8Array.allocate(10);
final arena = Arena(buffer, buffer.ptr.size);
final array = arena.newArray(5);
final array2 = arena.newArray(5);
void some_native_c_api(array.ptr, array.length, array2.ptr, array2.length);
arena.free();
