Visualise stack and heap feature suggestion

[dospore]

I am fairly new to rust but I was thinking about this as a potential project and thought I might as well contribute here.

Whilst learning I thought it would be a helpful and useful to visualise the memory whilst the code is executing. Most debuggers have this functionality so was thinking if I could add a debugger to the selection of tools. This might already exist or it might be too hard but was just checking and if not and its not super complex I would be happy to take this on as a learning project.

P.S. Sorry if this is not the place to discuss, I wasn't sure where to ask.
