Publishes the Scanco microCT test fixture `C0004255.ISQ` (107 MB) so it
can be referenced via `DATA{Input/C0004255.ISQ}` from the in-tree
IOScanco remote-module ingest (tracking ITK issue #6160).
Provenance:
- Upstream source: InsightSoftwareConsortium/ITKIOScanco test fixture
- File size: 106,958,336 bytes (102.0 MiB)
- Content sha256: c2a3750c75826cb077d92093d43976cc0350198b55edecd681265eebabfb438b
- CIDv1 (raw, sha2-256): bafkreigcun2qy5mcnsyhpwjaspkds5wmanibtc2v5xwnnajgl3v2x62drm
- File type: Scanco microCT scanner native .ISQ volume
Consumed by upcoming ITK PR for IOScanco ingest (issue #6160), which
adds Modules/IO/IOScanco/test/Input/C0004255.ISQ.cid containing the
CID above.

Publishes the two orphan `checkershadow_*.jpg` test fixtures used by the IsotropicWavelets test suite. These are referenced as raw JPEGs in the upstream ITKIsotropicWavelets remote module and must be republished as CID content-links for the in-tree ingest into ITK proper (ITK issue [#6160](InsightSoftwareConsortium/ITK#6160)). The remaining five IsotropicWavelets fixtures are already published as CID content-links in this repo (CID/bafkrei{f3k22q…,h6hdi2…,dmpadj…,ee4276…,dy2ng6…}) and require no changes. | Filename | CID | sha256 | size (bytes) | |---|---|---|---| | `checkershadow_gray_540x420.jpg` | `bafkreighex2biwhd5bzvoxbc3fu7k4irmlch6cdjx5mzwua4isisx6xi4a` | `c725f41458e3e873575c22d969f5711162c47f0869bf599b501c44912bfae8e0` | 62509 | | `checkershadow_illusion4full.jpg` | `bafkreid7i4fjtcxjhk6c6jobjgz4vpabjmyzcgx4sg75v53pamvbaun6iu` | `7f470a998ae93abc2f25c149b3cabc014b31911afc91bfdaf76f032a1051be45` | 181904 | CIDs computed locally via IPFS CIDv1-raw (`hashlib.sha256` + multihash prefix + base32-lower), matching every other blob in this repo. Zero-byte markers per the pattern used in PR #50; IPFS pinning (`w3 up`) will be performed by the maintainer prior to consumer use.

The forthcoming ITK PR for the IOScanco remote-module ingest (tracking
issue #6160)
adds
Modules/IO/IOScanco/test/Input/C0004255.ISQ.cidcontaining theCID above; ITK's
ExternalDatamachinery resolves it through theITKTestingData CID gateway.
IPFS pinning
The IPFS pin (
w3 up) for the 102 MiB blob is pending and will beperformed by the maintainer prior to merge, mirroring the manual step
used for PR #49.
