brew install pothosaudio fails (Catalina 10.15.6)

[kerrynwood]

Homebrew version 2.4.16

From source, I can get it to compile by changing -std=gnu++11 to -std=gnu+=14..

Its not the audio module, the executable from PothosCore is using the emplace_back of the bool specialization of std::vector. I guess they didnt add it yet until after c++11. Not sure, but it should be easy to switch it back to push_back() https://en.cppreference.com/w/cpp/container/vector_bool

I replaced the use of this function on master if you build with --head for pothoscore it should be fine

I have had a lot of random compiler issues to fix after this release so I think another tag is on the horizon. THanks for the report
