delete this misleading library

[batara666]

we should more educate people about *http.Request, *gin.Context and Gin's Midleware

It would be nice if there was an easy way to retrieve this information, but this module appears to take into account forwarded connections (via Proxy), among other things. Ideally, we could just get this information from the context, but I couldn't easily find it... I had started with something like:

	var baseURL string
	if c.Request.TLS == nil {
		baseURL = "http://"
	} else {
		baseURL = "https://"
	}
	baseURL += c.Request.Host // + c.Request.RequestURI
	log.Info("BaseURL: ", baseURL)

... which sorta worked until I deployed into K8s, where the load balancer was offloading https, then I needed to start looking at headers, and stumbled into this module. Instead of deleting it, we should probably "improve" it??
