Latest published version isn't working

thanks for updating reason-macros-bin, but I am having issues running latest published binaries. I could get it to run when I was manually copying the ppx for each platform etc.. but since you updated the library, bsb compilation is failing on my test project: you can see the pr here for a reproduction: https://github.com/sync/maccy/pull/4

First issue is that the ppx.js script needs to have execution permission set.

ninja: no work to do.

and if you check master it is working fine
sorry to be a pain 😃
btw once i change the permisison issue i get another error

Start by reproducing the published-binary failure with the reproduction PR linked in the issue, focusing on node_modules/reason-macros-bin/ppx.js and the builds of src/Icon.re and src/Index.re. Check both the permission-denied error and the later invalid-preprocessor-output error; done means the latest published binaries compile the reproduction successfully.
