Rewrite Meter_humanUnit() to accept floating point value
Since Meter_humanUnit() is often called with floating point values in
Meter objects, rewrite the function to let it process `double` type
natively, and save floating point to integer casts.
The rewritten function:
* Allows higher orders of magnitude including 'R' and 'Q', and
addresses infinity. (The previous version has a maximum value of
(2^64 - 1) representing 16 ZiB.)
* Rounds values when they are in intervals (99.9, 100) and (9.99, 10),
and displays them with correct precision (number of fraction digits).
* Produces assertion error on negative and NaN values (undefined
behavior).
