Use pathToFileURL (Windows fix)

[Maxim-Mazurok]

I was doing this:

import { dynamicImport } from "tsimportlib";
//...
const { default: filterAsync } = (await dynamicImport(
    "node-filter-async",
    module,
  )) as typeof import("node-filter-async");

And was getting this:

Error: Only URLs with a scheme in: file and data are supported by the default ESM loader. On Windows, absolute paths must be valid file:// URLs. Received protocol 'c:'

}

Fix inspired by nuxt/nuxt#19676

since the issue was fixed in #6, this pr needs to be closed

Yeah, your fix seems to work for me, likely even better than this one because looks like I put pathToFileURL to the wrong import.

I'm still having an issue #8 with this lib tho, will patch it up.
