* use llvm objcopy to rename syms
* use handlebars
* it works!
* remove linker code
* better docs internally about dev.dioxus.main
* use bundle identifier
* double check bundle identifier is proper

+/// This saves us from having to plumb the top-level package name all the way down into
+/// this file. This is better for modularity (ie just call dioxus' main to run the app) as

+/// change this, you'll need to change the CLI as well.
