Which team index and logo manifest the session has loaded and
where they came from: "live" (the SportsDataverse CDN, or the disk cache
within a day of it), "cache" (an older disk copy, after a failed
refresh) or "snapshot" (the copy bundled with the package: offline,
with options(sdvplotR.offline = TRUE), or during a CRAN check). The R
counterpart of sdvplot's versions().
