Directly set Approx's members in operator()
...
This avoids instantiating the member-setting function template
and checking the invariants in cases where we know the invariant
already holds.

Move Approx's validity checks out of line into cpp file
...
This avoids having to include <stdexcept> in the main include path
and speeds up the compilation if Approx is used with multiple
different types.

Introduced ReusableStringStream and removed all uses of std::ostringstream from the main path
...
ReusableStringStream holds a std::ostringstream internally, but only exposes the ostream interface.
It caches a pool of ostringstreams in a vector which is currently global, but will be made thread-local.
Altogether this should enable both runtime and compile-time benefits. although more work is needed to realise the compile time opportunities.

Approx rework: default scale == 0, epsilon applies to Approx::value
...
Also adds check to Approx::epsilon that the new epsilon has a valid
(ie one between 0 and 1)

The given epsilon should refer to the target value, otherwise
the result would be unexpected, e.g. 101.02 == Approx(100).epsilon(0.01)
is true.
The default scale should be invisible, thus,
e.g. 101.01 == Approx(100).epsilon(0.01) gets false.
Finally even 101.000001 == Approx(100).epsilon(0.01) is false
