Catena 4551 M102 pond sensor (with suitable patches) doesn't build with VMicro

I like to use Visual Micro because in many ways it works better than the Arduino environment.

However, it gets confused when I switch platforms on a project and ends up giving lots of errors. Seems more likely to happen on the 4551. I just saw that after patching the m102 pond sensor program to run with #include <catena.h> -- a lot of it was compiled with the SAMD architecture.

We need to get Sungjoon set up so he can test.
