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.

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

it's safer to just not use them until there's a more thorough
