[BuildScript] When doing a library build into a host package, the types piece of the build does not respect the output folder!

[birdofpreyru]

i.e. the buildCodeTypes() function (step of the build script) does not respect the -o command-line argument, and just builds into the path hard-coded into the tsconfig.types.json found by tsc, which is a problem for the intended use case, as the first step of the build it purges the types already present in the target destination.
