Windows color

Using this file:

~~~go
package main
import "github.com/apsdehal/go-logger"
func main () {
aa, _ := logger.New(1, 1)
aa.Warning("bbbbb")
}
~~~

I get this result:

~~~
[33m#1 2019-06-14 06:39:31 log.go:8 ▶ WAR bbbbb [0m
~~~

Reproduce the sample on Windows and inspect the logging path around log.go:8 to determine how the ANSI color codes are emitted. Done means warning output no longer displays literal [33m and [0m sequences on Windows; verify the observed output after the change.
