In addition to running with `go run` and creating a microfactory binary,
allow microfactory to be used as a package from other go tools as well.
To allow other packages to use this, it needs to be in a non-main
package, but `go run` requires a main package. So microfactory.bash runs
a sed script before running microfactory with `go run`.
This could also be solved by using a relative import, but neither
blueprint nor microfactory currently support that.
