v5.5.0

TensorOperations v5.5.0

Diff since v5.4.0

We are excited to announce TensorOperations v5.5.0, which consists of two main new features.

Firstly, automatic differentiation support now includes both Mooncake.jl and Enzyme.jl, on top of the already existing Zygote.jl support.
We hope that by providing native rules for our methods we can retain both runtime performance, as well as manage the compile time costs that are often associated with some of these AD frameworks.

Secondly, we added some additional functionality to better facilitate working with stack-like allocators.
This not only simplifies the internal implementation of the Bumper.jl support we already had, but also allows us to include a new BufferAllocator strategy.
Similar to how Bumper.jl works, this allocator can be used to avoid having to repeatedly allocate, especially when performing tensor contractions in a loop.
However, unlike Bumper.jl, this buffer does not require a maximal size, and can automatically adapt its size for the workflow, hopefully leading to a more convenient user experience.
