[feature request] Command to deploy macOS/iOS universal binaries

[gmeeker]

See the long discussion here:
#59

The simplest approach is to deploy the Conan dependencies, run lipo on everything, then use an Xcode project created by hand. My example command is here:

PR will follow shortly.

I have a different attempt here
#197

I'll probably close the deploy based attempt.
