Adapt to ReScript 11

[aantron]

There is still an issue remaining:

Thanks for the heads up! I've fixed some incompatibilities in 9439ba7, but I'm currently left with:

λ make -C test/js full-test

[...]

> node ./lib/js/hello.js

internal/modules/cjs/loader.js:818
  throw err;
  ^

Error: Cannot find module '/home/antron/code/bisect/bisect_ppx/test/js/lib/js/hello.js'
    at Function.Module._resolveFilename (internal/modules/cjs/loader.js:815:15)
    at Function.Module._load (internal/modules/cjs/loader.js:667:27)

    at internal/main/run_main_module.js:17:47 {
  code: 'MODULE_NOT_FOUND',
  requireStack: []
}

This is the former location of the output, hello.js, with ReScript <= 10. As far as I can tell, there is no output file at all now:

λ cd test/js && find lib                                                                                                                                          2

Could you suggest what changed in ReScript 11? I wasn't able to spot a relevant change in the changelogs for the ReScript 11 pre-release versions.

This appears to be a silent compilation error.
