Get SCANFI species layers without Google authentication

[eliotmcintire]

What

loadSCANFISpeciesLayers() now lists the SCANFI species-layer folder via reproducible::listGoogleDriveFolder() instead of calling googledrive::drive_ls() directly.

When a directory-remap manifest is set:

options(reproducible.urlRemap = "arbutus_manifest_SCANFI_v2_clean.csv")
# manifest built with buckethost::makeMirrorManifest(directories = TRUE)

the SCANFI files are enumerated from a public mirror (Arbutus object store) with no Google authentication — no Google account, no drive_auth(). The immediate use case is training/workshops, where participants can pull SCANFI layers anonymously.

Why this is safe / backwards compatible

• No manifest set → listGoogleDriveFolder() falls back to googledrive::drive_ls() and authenticates exactly as before. Identical behaviour.
• The per-file downloads already went through prepInputs(), so only the folder listing needed changing.
• The listing's url column is used directly (mirror URL when remapped, else the Drive file URL) instead of building https://drive.google.com/file/d/<id> — because the mirror listing carries no Drive id.

The change

Two lines in R/maps.R (loadSCANFISpeciesLayers):

- driveFiles <- as.data.table(googledrive::with_drive_quiet(googledrive::drive_ls(url)))
+ driveFiles <- reproducible::listGoogleDriveFolder(url)
...
- fileURLs <- paste0("https://drive.google.com/file/d/", driveFiles$id)
+ fileURLs <- driveFiles$url

Dependency note

⚠️ Requires the companion reproducible change that adds listGoogleDriveFolder() and directory-remap support (the type="dir" manifest column + byDir). That must be merged to reproducible@development before LandR CI here will pass. Once it lands, the existing Remotes: PredictiveEcology/reproducible@development picks it up; a reproducible (>= version floor bump in DESCRIPTION can follow when reproducible releases.

Scope

Only the loadSCANFISpeciesLayers site (maps.R:1520). The other drive_ls sites are intentionally left as-is (the kNN twin would also need shared_drive passthrough; the prepSpeciesLayers sites navigate Drive subfolder structure, not file listings).

Dependency is now concrete: requires reproducible (>= 3.1.1.9058), added in PredictiveEcology/reproducible#520 (listGoogleDriveFolder() + directory remaps). Floor pinned in DESCRIPTION. #520 should merge to reproducible@development first for CI here to pass.
