Check that `socialmixr` works in `renv` when running the targets.R file

[chitrams]

When Saras recreated the project (#35) she came across the issues:

• tar_make error for in_data_wpp object because socialmixr was not loaded
• Failed to install conmat automatically using renv, but when Saras did this manualy, it works. conmat failed to load because socialmixr failed to load
• furrr is missing?

Conclusion: socialmixr unstable, and we need to check that it loads correctly within renv? Also add furrr in lockfile

• Does it work when we use renv::restore()? This did not work for Saras
• Does it work once we've updated socialmixr in the lockfile?

Asked some other people (Yuval and Maurico) to run renv::restore() and will troubleshoot from their experiences.

The reason why this fails is because the conmat package is automatically downloaded from https://njtierney.r-universe.dev instead of https://idem-lab.r-universe.dev

When I tried to re-install conmat using pak, it didn't build, with the following error message:

The next steps are probably to:

• Clean the lockfile
• Reinstall conmat
• See if the lockfile records the correct repo for conmat
