LambertW: CI fixes.
...
Fix definition of lambert_w0_small_z_series_term.
Move rational approximations into smaller functions to try and keep msvc happy.

LambertW: Fix more CI failures:
...
Add fallback for 128-bit lambertW implementation.
Disable real_concept tests for msvc-12 and earlier as the compiler can't cope.

Lambert W: Add tests near the singularity.
...
Fix a couple of minor issues in the implementation to improve error rates.
NB: errors very near the singularity are still very high - this is an intrinsic property of the function - we are solving z = w exp(w) for w, but there are actually a wide range of w values which satisfy the equation once we get very close to the singularity.
