This PR has two commits. The first fixes a rather noisy compiler warning:
warning: ISO C++ forbids converting a string constant to 'char*'
The second commit is unrelated, but was a small housekeeping change as well. My system updated to PlatformIO 5 recently, and afterwards the ESP32 build failed because of a missing library. This adds that library. (Note that I haven't tested the addition beyond getting a successful build, I don't have an ESP32 to test with.)
