Vulnerability changelog

- 🔧 MAINTAIN: update requirement to `pyyaml~=5.4` (221)
The versions of `pyyaml` up to v5.4 contained severe security issues where the default loaders could be abused for arbitrary code execution.
The default `FullLoader` was patched to no longer allow this behavior, but as a result, data sets that could be successfully deserialized with it, now will fail.
This required using the unsafe `Loader` in for the deserialization of the exception state of a process.
