Following on from #125, this issue is to track improvements to the code for [gating activations in WaveNet layers](https://github.com/sdatkinson/NeuralAmpModelerCore/blob/e181f61efb8d05d34add45b5eecb3893ff21177c/NAM/wavenet.cpp#L38-L48).

See http://eigen.tuxfamily.org/dox-3.2/group__TopicStructHavingEigenMembers.html and act accordingly.

I.e. from https://github.com/sdatkinson/AudioDSPTools/blob/3db83678f00f936b87af61c1b2a55401fba54002/tools/CMakeLists.txt#L12

This library's namespace will be `audio_dsp_tools`
