Drops the AnalyzeObjectLabelMap remote-module declaration from ITK without ingesting the upstream into the source tree. Rationale and migration guidance in #6160 (this comment).

Why archive instead of ingest

The Analyze Object Map .obj format is a legacy format from the late 1990s / early 2000s era of Mayo Clinic's Analyze software. ITKAnalyzeObjectMap is essentially the only open-source reader/writer for it.

  • No other major open-source imaging package — Slicer, SPM, FreeSurfer, FSL, AFNI — supports the format.
  • The small residual user base of Analyze software (AnalyzeDirect, ~3 employees, still commercially sold) works inside that environment and is unlikely to need ITK's reader.
  • Upstream is maintained at minimum level (CI green, ITK 5.x API updates) but has zero stars, no releases, and the underlying format has been superseded.
  • Effectively dormant. Users with legacy Analyze Object Map data should perform a one-time conversion to NIfTI label maps and move forward.
Effect
  • Modules/Remote/AnalyzeObjectLabelMap.remote.cmake removed (54 lines).
  • Module is no longer reachable via -DModule_AnalyzeObjectLabelMap:BOOL=ON.
  • Upstream repository InsightSoftwareConsortium/ITKAnalyzeObjectMap remains read-accessible.
  • After this PR merges, the upstream repo should be flipped to archived=true. No Phase B ingestion-archival run is needed since nothing is being ingested into ITK proper — this is pure remote-module removal.

Fine with me. I never needed this. Maybe we should discuss this a bit more widely. Maybe call out this PR on the forum?

The Analyze Object Map .obj format is a legacy format from the late
1990s/2000s era of Mayo Clinic's Analyze software.  ITKAnalyzeObjectMap
is essentially the only open-source reader/writer for it.  The small
residual user base of Analyze software (AnalyzeDirect commercial
product) works inside that environment and is unlikely to need ITK's
reader.  No other major open-source imaging package — Slicer, SPM,
FreeSurfer, FSL, AFNI — supports the format.

The remote module has been maintained at minimum level (CI green,
ITK 5.x API updates), but has zero stars, no releases, and the
underlying format has been superseded.  Effectively dormant; users
with legacy Analyze Object Map data should convert to NIfTI label
maps once and move forward.

This commit drops the remote-fetch declaration so the format is no
longer reachable via -DModule_AnalyzeObjectLabelMap.  The upstream
repository at InsightSoftwareConsortium/ITKAnalyzeObjectMap remains
read-accessible for anyone needing the historical reader.

Addressed Greptile P2 in 9a8b40e (folded into the original commit): also removed the stale Module_AnalyzeObjectLabelMap entry from the mark_as_advanced(FORCE ...) block in CMakeLists.txt:920. Pre-commit clean, force-push lease-pinned.
