chore(dicom-codec): raise jpeg-lossless-decoder-js to 2.2.1

[wayfarer3130]

What changes

@cornerstonejs/jpeg-lossless-decoder-js moves from ^2.2.0 to ^2.2.1.
Two files change, and six lines.

2.2.1 restores the author metadata that npm dropped from the published package:
the manifest declared the author as an array, which npm does not accept, so
2.2.0 carried no attribution at all. 2.2.1 is also the first version that CI
published, so it carries a provenance attestation and 2.2.0 does not.

The decoded pixels cannot change

release/cjs/lossless.cjs and release/cjs/lossless.cjs.map are
byte-identical between 2.2.0 and 2.2.1. Only README.md and package.json
differ between the two tarballs:

$ diff -rq a/package b/package
Files a/package/README.md and b/package/README.md differ
Files a/package/package.json and b/package/package.json differ

The 102 dicom-codec tests pass, 7 skipped, and that count includes both
byte-exact JPEG Lossless comparisons. The .70 SV1 fixture is the regression
case for the end-of-scan fix, and it fails on any decoder without the fix.

This pull request is also a CodSpeed control

A benchmark that this pull request flags is noise, because the executed code
does not change. That makes this a useful measurement of the reports
themselves.

main holds a real baseline for the first time in a while. The merge of #94
(acc43f1) did not seed one: build (big-endian) failed with wget exit
code 4, a transient network error while it fetched cmake 3.17.4, and one
non-success among the nine build jobs makes bench.yml's gate skip the bench —
while the Bench run still reports success. Re-running that job and then
dispatching bench.yml on main seeded the baseline (run 34608677463,
codspeed-bench success).

pnpm-workspace.yaml needs no change here, so the gate benches dicom-codec
alone rather than a full sweep. Its minimumReleaseAgeExclude entry names the
package and no version, so a new release of the package installs without an
edit. A version-pinned entry, which is what pnpm writes by itself, would have
failed this install.
