@willmcgugan I have added the discussed feature, let me know in case anything else is required

[willmcgugan]

Rather than "decimal_suffix", let's call it "binary_units" which should default to False.

Note typo in attribute name

Alright!!

@willmcgugan Sorry for some unnecessary commits, I think this should be it let me know in case you need something else, should I also resolve conflicts in Changelog?

[willmcgugan]

LGTM. Thanks.
