Getting tab order programmatically

[DimasVoxel]

Is your feature request related to a problem? Please describe. Currently, there is no way of getting the order of the tabs in a tab bar. Getting the children of the tab bar only outputs the order in which the children/tabs were created.

Describe the solution you'd like Having a new function to either get the order of the tabs in the tab bar, or having get_item_info have the order included.

Additional context Currently, it is possible to get the get_item_rect_max and deduct the order using where the actual tab is drawn. This breaks when the UI is still staged and not yet drawn and will always output 0 0 in that case.
