modernize jaspTools a bit

[vandenman]

We should:

• use rappdirs for the location of the clone of jasp-stats/jasp-desktop.
• use gh to do the github interactions.
  • use some setting to update this clone (update: [always | ask | never]
  • have an exported function to update the clone as well
• do not install all jasp-packages for a user, also do not ask if a user wants to do this.
• do ask if a user wants to restore the renv lockfile if the library does not match.
  • use some setting for asking this (restore lockfile: [ask | never]
  • do not have an exported function to do the restore, but make it clear this just call renv::restore.
• offer to use pkgload::load_all when calling runAnalysis rather than reinstalling the module everytime.
  • use some setting for asking this (restore lockfile: [pkgload::load_all | install | nothing]
