Advice provider playground update

[frisitano]

This PR achieves the following:

• Updates object names associated with ProgramInputs (operand_stack, advice_stack)
• Adds support for advice_map and merkle_store
• Refactors input and output validation such that errors are provided via the UI
• Refactors miden-wasm backend to return Result<_, JsValue> type and never panic
• Updated front end to parse errors returned from the miden-wasm backend and display them to the user

TODO:

• update typescript test suite to account for the logic above.
• Add updates to epxlainer.

Call to action: It would be great if we could collaborative test the experience to ensure that the tests which have implemented are stabled.

@frisitano thanks a lot. That looks great. I left some nits and questions. And in general, I am not sure if we should allow those complex inputs like merkle_store in the playground. There is certainly no harm in doing so, but because you cannot create those data structures in the playground, I would expect users to use the CLI anyway for this.

And we need to change all the other examples as well because they don't work now anymore. I can do that after your PR is merged

Thank you for the review!

I think it's quite important that we provide support for merkle data structures as they form the basis of a lot of useful applications as mentioned in my response above. However, I do agree that we need to build better support for actually building the merke store inputs.

And we need to change all the other examples as well because they don't work now anymore. I can do that after your PR is merged

I have a PR lined up for this: https://github.com/0xPolygonMiden/examples/pull/119/files

I am convinced, let's do that.
