Bun support for relay-compiler

I changed my projects' package manager to Bun and when I run relay-compiler with `bun`, it throws below error. It only works with `yarn`. I have no idea how to tackle this issue 🤔

```
> dooboo@1.0.0 relay
> relay-compiler

HINT: pass --watch to keep watching for changes.
Error: Cannot find module 'relay-compiler/lib/transforms/FlattenTransform'
