[Feature request] RMarkdown: "Run all chunks" & "Run previous"

[pat-s]

RStudio has the nice feature to "Run all chunks" or "Run previous" for RMarkdown documents. This is really handy if you want to have all objects up to a certain chunk to continue from there.

Currently I need to c/p each chunk by hand to the R interpreter to avoid errors when pasting text to the interpreter.

(To run all chunks, this custom function can be used as a workaround.)

This could be done as extension command that detects the code chunk the cursor is at. And we could also do this using CodeLens like vscode-python:

I started working on this in #49 but stopped before producing any useful shareable code. If someone else wants to add this feature that would be very welcome of course!

Using a CodeLens would be a nice approach.
