RuntimeError: dictionary keys changed during iteration

[davidohana]

I could not reproduce the RuntimeError: dictionary keys changed during iteration issue under Python 3.8 (added a CI build with Python 3.8 which did not raise this exception). However, for the robustness of the code, I did some refactoring to avoid the str-to-int type conversion on load at all. This should solve it.
jsonpickle also updated to v1.5.1.

For what it's worth, persistence lead to this exact error on v0.9.1 (using the examples to make it easier to reproduce):

• On Python 3.9.1, persistence to a file lead to this result.

Starting Drain3 template miner

Traceback (most recent call last):

• On Python 3.8.7, it works
• On Python 3.8.0, it works

Do you get this error also on v0.9.2?

[Sayrus]

It is fixed on v0.9.2 !
(Editing the previous message, I did not update the dependency to check on the new version)
