Cannot use write_svg, when two object has the same sequence number.

[MarievB]

When I use write_svg(), I get the following error:

File "C:\Users\Me\AppData\Roaming\Python\Python39\site-packages\pydotplus\graphviz.py", line 1640, in to_string
    obj_list = sorted([
TypeError: '<' not supported between instances of 'dict' and 'dict'

When I print the objects in the obj_list, I can see that there are several objects with the same sequence number, which leads the sorted() function to compare the objects that are dictionaries, which obviously it cannot. I do not manually change any sequence numbers, so that happens automatically. How do I avoid multiple elements having the same sequence number? I am automatically generating > 19,000 graphs, so manually is not an option :)

Thanks for an otherwise super great package btw!

EDIT: I have "fixed" it locally by just not sorting the obj_list, but I do not really know the consequences of this.
