Is your feature request related to a problem?

The most current version of xarray only seems to support the "least_significant_digit" compression. As of version 1.6.0. of netcdf4-python, thee option to specify "significant_digits" is available. This allows specifying the total number of digits rather than the digits after the the decimal point and is therefore independent of magnitude. https://unidata.github.io/netcdf4-python/#Variable.quantization

Describe the solution you'd like

Allow python ncoding={myvar:{'dtype':'float32', 'zlib': True, 'complevel':5, 'significant_digit':7}, 'time':{'units': 'days since 1800-01-01'}}

Describe alternatives you've considered
