Return different meshcode values included in the mesh.
mesh_convert(meshcode = NULL, to_mesh_size = NULL)character. mesh code
target mesh size. That is, 1 for 1km, and 0.5 for 500m. From 80km to 0.100km.
If NULL for to_mesh_size, the meshcode of one small
scale will be returned. If it is the same as the original size,
the meshcode of the input will be return.
