Check whether codecarbon is installed and importable
Value
TRUE if codecarbon can be imported, FALSE otherwise (including
when no Python interpreter can be found at all).
Examples
# \donttest{
# Not \dontrun{} -- this genuinely works, it's just slow: on a machine
# with no Python configured (e.g. a fresh CRAN check environment),
# reticulate's interpreter discovery alone can take >10s before this
# returns FALSE. \donttest{} keeps it out of the default check timing
# while still letting CRAN's extended checks and interactive users
# verify it actually runs.
carbon_tracker_ready()
