Incorporating unit offsets into the internal "value" of the unit
causes more problems than it solves. This commit ends that practice
and instead only uses the offset when converting units or when
computing the absolute value of a unit.
Further, it makes it an error to compute the sign of a unit with an
offset, since that is inherently ambiguous: there is no way to tell
whether "-5 degC" is a temperature change, in which case it is definitely
negative, or if it is a specific temperature of something, in which case
it is "positive" in the sense of being above absolute zero.
(Unclear how valuable this latter concept is anyway, given that there are
no negative temperatures possible in that sense...)
Adds several tests for the various problems the former practice caused,
including all four basic arithmetic operations on units with offsets.

* fix qr and sign edge cases
qr() was throwing an error if the pivots of a matrix were zero.
This commit fixes that and ensures that the results are consistant
with wolfram alpha.
Whilst doing this I found a bug in complex.js, I have added a work
around but we should flag this upstream.
I also addressed the long standing concerns about assert statements
within the body of the qr function.
Fixes#1669Fixes#942
* further improvements to qr and sign
mainly fixing things I got wrong in previous commit
* add array test
* fix: remove only from tests and disallow
Uses mochas `--forbid-only` flag as advised by
https://github.com/standard/standard/issues/988
* Fixed unit base recognition and formatting for user-defined units
* Manually copied work from another branch
* Removed semicolons
* Replaced assert.equal with assert.strictEqual
* Added support for bignumber
* Replaced var with const
