c917f264c4 quaternion: fix incorrect factorisation in as_matrix
One of the terms in m[0][0] and m[1][1] was incorrectly negated from an
incomplete factorisation when I transcribed the formula.

Also reintroduces the axis-rotation tests which inadvertantly had zero
magnitudes.

3d5aff0f30 maths: use mult rather than negation in constexpr
util::digits was triggering signed overflow warnings under gcc. By using
negative multiplication rather than explicit negation we get the same
behaviour, sans warning.

45795a1ae0 quaternion: compare test results using sum-of-differences
comparison of floating point values is inexact and there isn't an easy
way for providing an ULP delta via the TAP interface. morever, the
general expected error is too large to reliably express in ULPs.

7b4ece207b matrix: remove static_assert size testing
accessing the static size data via a class instance is unwiedly, but we
should have identical protections due to the template parameters

de48f75e96 format: fix transcription of zero values to strings
an iteration condition terminated the write when a value was zero rather
than when all numerals were written. instead, iterate over the remaining
numerals.
