We have cordova hooks in our source folder (see the cordova hooks guide for more info: https://cordova.apache.org/docs/en/dev/guide/appdev/hooks/) that need to be copied into our destination folder and need to preserve the executable bit on their file mode (i.e. ls -l should print -rwxr-xr-x for these files).

Currently this doesn't happen, but it seems like it should be easy to do by passing a options object as a 3rd parameter to the to the fs.writeFileAsync() call in the writeFilePromises with the stat.mode from the fs.statAsync() call.
