Removed misleading/unnecessary use of ImGuiButtonFlags_AllowItemOverlap in BeginSubplots(). (#203)
Fixes for 1.89.7 renaming + new ImGuiButtonFlags_AllowOverlap behavior handled by ButtonBehavior() fixes other items from hovering while dragging plot.
Added a bit of ifdef machinery so changes will also work with older versions of ImGui.
