feat(reflection): Bring in new libconfig

This version of fourdst (v0.9.14) brings in the version libconfig which
includes reflection based config filed (v2.0.2).

This is a breaking change as any code which used versions of libconfig <
v2.0.0 will no longer function when linked against this version of
fourdst
