What kind of change does this PR introduce?
New func xs.io.round_bits to round a floating point variable up to a number of bits, allowing for a much better compression afterwards.
New "bitround" arg to save_to_zarr and save_to_netcdf, allowing to combine the bit rounding and the saving. The argument can take many forms for more flexibility.
Does this PR introduce a breaking change?
No.
Other information:
Default keepbits value is guessed from the variable name, with a default of 12 (0.0122% of rel error). Better guesses should be given in xs.io.KEEPBITS, but I have none for now.
