Error [ERR_UNSUPPORTED_ESM_URL_SCHEME] when using a artillery runner file with a .mjs extension

[thrandale]

Artillery is supposed to support ES Modules. Per the documentation, the way of doing this is to have your artilleryRunner file have the .mjs extension instead of the .js extension. I am using an artillery.yaml file to pass in the processor:

config:
  ...
  processor: "artilleryRunner.mjs"
  ...

When running artillery it gives the error Error [ERR_UNSUPPORTED_ESM_URL_SCHEME]: Only URLs with a scheme in: file, data, and node are supported by the default ESM loader. On Windows, absolute paths must be valid file:// URLs. Received protocol 'c:'

In doing some tracing, this error is Coming from core/lib/runner.js when it is trying to load the artilleryRunner.mjs file. Per this) Stack Overflow Post: the import() function [only works with file:// and data:// URLs](https://nodejs.org/api/errors.html#err_unsupported_esm_url_scheme), but path.resolve() only returns an absolute path (not a URL)

This can be fixed by doing a pathToFileURL() before doing the import() of the module
