Release v0.13.11

[lkdvos]

MPSKit.jl v0.13.11

A maintenance release with notable performance improvements to core contraction routines, alongside TensorKit / TensorKitManifolds / MatrixAlgebraKit compatibility updates, GPU groundwork, and a number of bug fixes.

Highlights

• Performance: AC and AC2 contraction routines have been optimized, reducing allocations and runtime in DMRG/VUMPS hot loops; a benchmark suite has also been added to track this going forward (#345)
• Preparations for GPU / non-CPU array support (#375, #392)
• Refactored time-evolution MPO construction (#422)
• Compat bumps for TensorKit, TensorKitManifolds 0.8, and MatrixAlgebraKit (#416, #421, #418)

@maartenvd I will try and release this first, and schedule the window hamiltonian changes for a follow-up if you are okay with this.

Why were these tests cancelled? Runtime?

[lkdvos]

Unfortunately yes. This is definitely something on my list of things to start looking into, it is a combination of many different effects, which also somehow tends to randomly pan out in different directions. I have a feeling the "running tests in parallel" combo with the compilation-heavy workload is what is causing this, but I should also just split up the tests a little bit more.
Unfortunately this all takes a lot of time, and I really need another release out to unbreak a bunch of things 🙃
