Demonstrate running Julia operations within RQ

[fivegrant]

Goal

We currently use RQ to run python simulations (e.g. pyciemms). This issue is to explore whether it is possible to create RQ jobs that perform simulations using SciML/EasyModelAnalysis.jl.

Approach

Port a simple simulate operation from the SciML service and use PythonCall.jl to implement it within an RQ worker job.

Why it matters

If successful, we'll be able to have a single REST layer for simulation management that appropriately routes jobs to either pyciemms or sciml. It will allow for a more unified user experience in the HMI and a simplified integration with the HMI server.

#26 is necessary since we don't want to install julia onto the same image as the api
