initial build settings for osx-arm64

Fixed expectation of fortran order data

Previous versions expected data in fortran order. A workaround was to supply volume.T with C-order data to march. This should not be done anymore. march works with C- and F-order data now.

Fixed number of iterations

Making this a new version since the behavior change after fixing the number of iterations in smoothing (#23) is quite impactful for the functionality of this package.

Due to a bug, the result of Laplacian mesh smoothing algorithm would correspond to one round less.

Stable release, building properly on all platforms
