Calamares crashes when calling setprogress()

[dalto8]

Describe the bug
When a Python modules calls libcalamares.job.setprogress() too quickly the application crashes.

To Reproduce
Steps to reproduce the behavior:
Run this code:

while True:
    libcalamares.job.setprogress(0)

Expected behavior
Instead of crashing, it would be preferable to set the progress amount/message.

Confirmed (this is a dup of something, related to crashes in the packages module when pacman progress-reporting is enabled, isn't it?) Easy to reproduce, although replacing the while with something like for r in range(100000) doesn't trigger it for me.

It is definitely the same issue that has been discussed elsewhere. I opened this because I didn't think we had an open issue to track it.

With pybind11, this stress test passes, with Boost, it crashes as reported. Closing with "we should be using pybind11 in future".
