add support to install this buildpack in different paas providers than just heroku (im trying to set this buildpack in railway currently).

Took a quick look at this the other day and I think we would also need to make the buildpack conform to the Cloud Native spec.

you need to setup the package.toml and buildpack.toml i think, maybe rename /bin/compile to /bin/build.
i dont have docker setup to test it.
