update rtd-pip-requirements to allow doc build

sometheing the docs are doing requires sphinx>=1.4.2. There was a bug in 1.4.1 that caused an error if a caption was not supplied to TOC. sphinx-doc/sphinx#2465 added other requirements such that local build worked installing just from rtd-pip-requirements from a blank conda env.
