Excessive failures and solve times

[Plootie]

Firstly if this has been answered in any of the previous issues i'm very sorry, i did read through them but those issues don't seem to be the same as what i'm experiencing. This library was working great for me for a few days and i loved it, no need for node.js and simple to use but yesterday i just kept getting clearance fails. i decided to try again the next day but kept getting clearance fails again so i set retries to 9 and delay to 10,000 as a last ditch effort and while it did eventually work it took 90 seconds (92946ms exactly) to get to the page which isn't particularly great. My test code is here

@Plootie you got the s-parameter there. try my S-Parameter branch with a delay of 4000ms!

After some trials, I noticed:

• S parameter has to be Uri.EscapeDataString, otherwise even if the calcultated answer is fine, the request will fail "randomly".
• if you use User-Agent Client 1.0, you get both success and failure events... better to put a recent standard user-agent in the system instead of Client 1.0

• if you also add the following headers Accept, Referer and Upgrade-Insecure-Requests

  if (response.RequestMessage.RequestUri != null)
              clearanceRequest.Headers.Add("Referer", response.RequestMessage.RequestUri.ToString());
  
  clearanceRequest.Headers.Add("Accept", "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8");
  clearanceRequest.Headers.Add("Upgrade-Insecure-Requests", "1");

  It appears to finally give a 100% rate from my trials.

I added a pull request implementing all of these #43 (big thanks to @Bleialf and @Zaczero)
