API use fails as of 1.2.2

[Tim McMackin]

I was working on upgrading to 2.0.0 from 1.2.1 and I've traced a problem to the upgrade from 1.2.1 to 1.2.2.

With 1.2.1 I can do this:

const apiFilter = require('openapi-filter');

async function filterInternalRoutes(docPromise, filterTags) {
  const openApiDocument = await Promise.resolve(docPromise);
  return apiFilter.filter(openApiDocument, {
    tags: filterTags || ['x-internal', 'x-alpha'],
  });
}

When I do that in 1.2.2, I get this error:

Usage: openapi-filter [options] {infile} [{outfile}]

Options:
  -h, --help     Show help                                             [boolean]
  --version      Show version number                                   [boolean]
  -i, --inverse  output filtered elements only                         [boolean]
  -t, --tags     tags to filter by             [array] [default: ["x-internal"]]

Did the way openapi-filter API is invoked change in 1.2.2? Same error with 2.0.0.

Thanks for reporting this. PR #5 broke the API support for requireing this module and I didn't notice.

Should be fixed in v2.0.1. Note you'll have to change the option tags to flags.
