[unconfirmed] Generate a code run interactively, in R

[soniamitchell]

Read and write functions could generate a user-written config.yaml on the fly when working locally and interactively in R (without using the CLI).

When querying the registry, a call would be made to the fair CLI, which would query the registry itself, and return the appropriate information.

• In this case, do we even need a config.yaml file if the information is written to the handle? Can't the working config.yaml be written retrospectively, in finalise()
• Use initialise(local = TRUE) to initialise the code run
