Wildcard parameter - allow developers to retrieve the wildcard parameter from URL

[guilherme-s3wf]

Currently, wildcard parameters in the API route URL are not accessible. It would be beneficial to allow developers to retrieve and utilize the value of the wildcard parameter from the request URL. This enhancement will improve the flexibility of routing by enabling dynamic behavior based on the URL structure, making it easier to handle various use cases that depend on path segments.

Usage example:

q.Get("/v1/user/*", func(c *quick.Ctx) error {
	return c.SendString("User: " + c.Param("*"))
})
