`dpg.add_area_series()` can't fill area when axis `invert=True`.

## Version of Dear PyGui

Version: 1.6.2
Operating System: Windows 10

## My Issue/Question

`dpg.add_area_series()` can't fill area when axis `invert=True`.

## To Reproduce
```
import dearpygui.dearpygui as dpg
dpg.create_context()
with dpg.window(label="main", height=600, width=600,tag="main_window"):
with dpg.plot(label="Area Series", height=400, width=-1):
xaxis = dpg.add_plot_axis(dpg.mvXAxis, label="x")
yaxis = dpg.add_plot_axis(dpg.mvYAxis, label="y", invert=True)
dpg.add_area_series([1,5,3],[0,0,3], fill=[255,50,100,190],parent=yaxis)
dpg.create_viewport(title="test")
dpg.setup_dearpygui()
dpg.show_viewport()
dpg.start_dearpygui()
dpg.destroy_context()
```

## Expected behavior

`dpg.add_area_series()` should fill area when axis `invert=True`.
