Hello.

I have identified a data race on the pterm.SpinnerPrinter.

General information:

• pterm version: v0.12.57
• go version: v1.19.7
• os: windows

Steps to reproduce:
run following code with go run -race

p, err := pterm.DefaultSpinner.
    WithShowTimer(false).
    WithRemoveWhenDone(true).
    Start("Doing stuff...")

if err != nil {
    log.Fatalf("Start spinner failed: %s", err.Error())
}

time.Sleep(2 * time.Second)

err = p.Stop()
if err != nil {
    log.Fatalf("Stop spinner failed: %s", err.Error())
}

After inspecting the source code i have found out that the reason is the go routine, spawned in func (s SpinnerPrinter) Start(text ...interface{}) (*SpinnerPrinter, error)
