maths: only enable util::limit for scalar types
...
this reduces conflicts with the coord limit operation.

coord: don't use kahan summation for sum(coord)
...
Our kahan summation algorithm has issues with infinities so we just
avoid using it in coordinates where speed and simplicity are more
important.

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.

maths: add integer summation path for fsum

this allows us to simplify users of fsum which may not care what
value_type they're passing for summation

format: reimplement format rendering
...
requires literal string arrays, and implements more of the specifier
specification. does not implement 'n' or '$' specifiers. falls back to
snprintf for real arguments.

maths: make stirling inline rather than constexpr
...
stirling uses cmath functions which aren't constexpr, such as std::pow.
this sometimes works under linux/gcc but fails under clang/freebsd

maths: remove const/pure attributes
...
const/pure attributes are causing inconsitencies for various functions.
it's safer to just not use them until there's a more thorough
investigation of their impact.

almost_equal only operates on two reals, or two integers (and even then
only on the same signedness).
