I believe this should go in the 0.23 section

Ok, I will fix CHANGELOG.md
I have a question. Although, I didn't change function hermite_multidimensional in _hermite_multidimensional.py, it compatible with a list cutoff by design. Should I change the documentation of this function?

Context:
'cutoff' argument for the 'density_matrix(mu, cov, post_select, normalize, cutoff, hbar)' function from 'fock_tensors.py' is the same for all modes
Description of the Change:
Added support of the 'list' type of 'cutoff' argument for the 'density_matrix(mu, cov, post_select, normalize, cutoff, hbar)' function from 'fock_tensors.py'. It enables to perform larger simulations.
Example: 4 bosonic modes
Hilbert space dimensions 20 for each mode => ~380 GB of RAM for a density matrix.
Hilbert space dimensions 20 for 2 main and 3 for auxiliary modes => 200 MB of RAM for a density matrix.
Benefits:
Enables users to choose different Hilbert space dimensions for different modes of a density matrix. It can be helpful for simulations with a large number of modes.
Possible Drawbacks:
None
