Print logs on top and bar at bottom

[fenollp]

In trying to reproduce the apt progress bar I adapted https://github.com/gosuri/uiprogress/blob/ec0f254bbca2b17ed68f18af8773a0527b522f01/example/simple/simple.go so that some lines are printed:

package main

import (
        "time"
        "fmt"

        "github.com/gosuri/uiprogress"
)

func main() {
        uiprogress.Start()            // start rendering
        bar := uiprogress.AddBar(100) // Add a new bar

        // optionally, append and prepend completion and elapsed time
        bar.AppendCompleted()
        bar.PrependElapsed()

        i := 0
        for bar.Incr() {
                time.Sleep(time.Millisecond * 20)
                i++
                if i % 10 == 0 {
                        fmt.Println("Well hello there")
                }
        }
}

I'd like for the lines to print above the progress bar, which would stay at the bottom. However I'm only getting duplicated progress and only one line printed (also not at the right place but I'm sure that's another issue):

   0s [=====>--------------------------------------------------------------]  10%
   0s [============>-------------------------------------------------------]  20%
   0s [===================>------------------------------------------------]  30%
   0s [==========================>-----------------------------------------]  40%
   0s [=================================>----------------------------------]  50%
   1s [========================================>---------------------------]  60%
   1s [===============================================>--------------------]  70%
   1s [======================================================>-------------]  80%
   1s [=============================================================>------]  90%
   1s [====================================================================] 100%
Well hello there
