FoldsThreads: Extra threaded executors for JuliaFolds2/*.jl

FoldsThreads.jl provides extra thread-based executors usable with various JuliaFolds/*.jl packages such as Transducers.jl and FLoops.jl.

(* ThreadedEx is the default executor provided by Transducers.jl)

• WorkStealingEx implements work stealing (continuation stealing). Useful for load-balancing.
• DepthFirstEx implements depth-first scheduling. Useful for findfirst-type computations.
• TaskPoolEx: Task pool executor. Useful for fine execution control (e.g., back pressure and "background" threads).
• NondeterministicEx: An executor for parallelizing computations with non-parallelizable iterators.
