FitPadding Style target out of range

[JackNewman12]

Version of Dear PyGui

Version: 0.8.64
Operating System: Windows 10,

My Issue/Question

I cannot seem to set dpg.mvPlotStyleVar_FitPadding. It also applies to a few more of the "2 value" plot theme settings but I haven't created a list of all of them.

To Reproduce

Minimal code to reproduce:

from dearpygui import dearpygui as dpg

with dpg.theme(default_theme=True) as t:
    dpg.add_theme_style(dpg.mvPlotStyleVar_LineWeight, 2, category=dpg.mvThemeCat_Plots)
    dpg.add_theme_style(dpg.mvPlotStyleVar_FitPadding, x=0.05, y=0.05, category=dpg.mvThemeCat_Plots)

dpg.start_dearpygui()

Which then crashes:

Exception: Error: [1000] Message:       Style target out of range.

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "C:\Users\Jack\Documents\guitest\fitpadding.py", line 5, in <module>
    dpg.add_theme_style(dpg.mvPlotStyleVar_FitPadding, x=0.05, y=0.05, category=dpg.mvThemeCat_Plots)
  File "C:\Users\Jack\Documents\guitest\ENV\lib\site-packages\dearpygui\dearpygui.py", line 5308, in add_theme_style
    return internal_dpg.add_theme_style(target, x, y, label=label, user_data=user_data, use_internal_label=use_internal_label, id=id, parent=parent, category=category)
SystemError: <built-in function add_theme_style> returned a result with an error set

I have tried a bunch of different ways of inputting the data (tuples / with or without the category / etc) but it never seems happy.

Hopefully this is not just user error,, although if it is perhaps some more demo code would help.
Currently loving the library! Thanks for all the hard work.
