Traffic: [Status 101] - The status provided (101) is outside the range [200, 599]

Description

If the user uses a .har file that contained a websocket entry , this package will throw an exception:

Uncaught (in promise) RangeError: Failed to construct 'Response': The status provided (101) is outside the range [200, 599].

    at fromTraffic (@mswjs_source_traffic.js)

Reproduction steps

Go to a site that open a websocket (your dev env might be enough if it has a fast-refresh)
Open your network and look for a WS resource (like ws://localhost:3006/ GET 101 Switching Protocols)
Export the logs as HAR file
Try to generate the request handlers following the instructions

HAR file

test/traffic/fixtures/archives/entry-with-ws.har

Test template

  it(
    'does not throw an exception given an HAR file with a websocket entry',
    () => {
      const traffic = readArchive(
        'test/traffic/fixtures/archives/entry-with-ws.har',
      )
      expect(() => fromTraffic(traffic)).not.toThrow()
    },
  )

Expected behavior

It would be ideal if the library didn't throw an exception, or if we could add an entry in the documentation advising users to filter those entries in HAR before using it.

Workaround

fromTraffic(traffic, (entry) => {
  if (entry._resourceType === 'websocket') {
    return
  }
  return entry
})
