The lfiz tool works on the binary part (LFI file) of a FM
file, synchronous or diachronic. It is a lossy compression tool.
The compressed articles are exclusively the 2-dimensional or
3-dimensional REAL fields.
This will produce the compressed file myfile.Z.lfi
The unlfiz tool will restore the 64-bit REAL value size to all
the compressed LFI articles.
