It seems to me that `ParallelDataTransfer.jl` is discontinued - the project still misses `project.toml` file and uses `REQUIRE` - this blocks the package from being installed in recent versions of Julia.

My question is - is there a successor or a replacement package for data transfer between workers? Or a workaround? I’d like to know before starting PRs to support `ParallelDataTransfer.jl` in my workflows on Julia 1.8.

I haven’t touched it in a long time, but is anything broken with it? It wouldn’t be too difficult to check. It’s a relatively simple package and only dependent on Base, so I’d be surprised if much needed to be changed. I’d assume it would take like half an hour to get the actions setup and get it back alive. If that’s done, I’d also move it from my personal account to SciML to get other maintainers on it.

Run the tests locally and see if it’s still running.

It looks like it’s working just fine:

Hi Chris,  
sorry for the false-positive report. The problem I was facing was in my part of the code - I suspected the ParallelDataTransfer to be the root-cause, I tried to `]dev` it and it failed in the dev-process as julia didn’t find the `Project.toml`. It looks like for the dev-clonning the package needs the `Project.toml` set-up. I’ll keep the issue open - I’ll hopefully find some time to do a Project.toml PR soon.
