1D ArrayLike data as input

[naoak]

Hi,
MarchingSquaresJS requires 2-dimensional input data, but i have very huge 1-dimensional ArrayLike data (e.g. Float32Array). Is there any better way than converting it to 2D data? One thing I'm thinking about is to support multi-dimensional arrays like ndarray whose data source is 1D ArrayLike but can be accessed as like 2D array by get/set methods.
Any thoughts?
Thanks.

I've managed to achieve this. Here is sample codes.

We were able to reduce the memory usage compared to generating a 2D array. However, the performance of index access was 20 to 400 times worse due to the use of proxies.
