Additional functions for array.
 remove_duplicates(array_in) 
  Remove duplicates in array.
  Parameters:
     array_in : (int /float /string ) Array contains duplicates.
  Returns: Array without duplicates.
 // Example: int 
import tuele99/xarray/1 as xarray
c = xarray.remove_duplicates(array.from(1, 4, 2, 1, 2))
plot(array.size(c))
plot(array.get(c, 0))
plot(array.get(c, 1))
 // Example: float 
import tuele99/xarray/1 as xarray
c = xarray.remove_duplicates(array.from(1.0, 4.0, 2.0, 1.0, 2.0))
plot(array.size(c))
plot(array.get(c, 0))
plot(array.get(c, 1))
 // Example: string 
import tuele99/xarray/1 as xarray
c = xarray.remove_duplicates(array.from("green", "red", "green", "red", "green"))
plot(array.size(c)) // value = 2
label0 = label.new(x=last_bar_index, y=0, yloc=yloc.belowbar, text=array.get(c, 0), style=label.style_label_left, color=color.new(color.black, 100), textcolor=color.green) // below text = "green"
label1 = label.new(x=last_bar_index, y=0, yloc=yloc.abovebar, text=array.get(c, 1), style=label.style_label_left, color=color.new(color.black, 100), textcolor=color.red) // above text = "red"
