Serious flaw in usage example shown in Readme

[nelsonad]

As described in this article, https://aspnetmonsters.com/2016/08/2016-08-27-httpclientwrong/, an application should limit the number HttpClient objects that are created and reuse it for subsequent requests. Otherwise it would open a new TCP connection for each request and it would be very easy to hit an application pools max queue length of 1000 for any website using this code as is.

The sample code in the readme should add a disclaimer describing the issue or be updated to a more complete implementation.
