Integration of JET.jl in CI Pipeline

[jeleclaire]

We run report_package from JET.jl from time to time locally to detect type instabilities. In the past, it has tended to generate verbose outputs for our dependencies making it hard to find critical points in our library. Further analyses are needed to check the output and implement filtering if necessary.
As suggested by vboussange we should strongly consider to integrate it into our CI Pipeline.

• [] implement filter for output
