Fix chunk size check

[ealerskans]

Describe your changes

Updates check_chunk_size to use the actual dimensions of the data-array to estimate the memory usage of the chunking. It also corrects the warning print statement. Previously, it was assumed that all variables have the same coordinates, but now the coordinates for each individual variable is used to estimate the size bytes for a chunking of that variable.
