small round tripper to avoid triggering the "attention required" status of CloudFlare for HTTP requests.

It'll add required/validated headers on requests and update the client TLS configuration to pass the CloudFlare validation.

This is (at least so far) **NOT** intended to solve challenges provided by CloudFlare, only to prevent CloudFlare from directly displaying you a challenge on the first request.

The bypass is tested on a schedule everyday at 3 AM in case CloudFlare updated their detection, so the badge is always displaying if the bypass still works.

## Dependencies

- [eddycjy/fake-useragent](https://github.com/EDDYCJY/fake-useragent) - for setting a believable request user agent.

CloudFlare is relatively forgiving with the user agents anyways but it'll add some variety for the long term.

## Usage

You can add the round tripper as any other round tripper:

```go

client := &http.Client{}

client.Transport = cloudflarebp.AddCloudFlareByPass(client.Transport)

```

small notice:  

Using the http.DefaultTransport will currently still fail, nil or empty &http.Transport works.

Didn't have the time to check what exactly is different causing the CloudFlare validation to fail though.

## Development

Want to contribute? Great!  

I'm always glad hearing about bugs or pull requests.
