Adds support for Korea-era encrypted new OJN wrappers, which 1.0.0 rejected
outright. They are decrypted transparently -- pass the file exactly as you would
an ordinary one, no extra option needed.
What's new
- Korea-era
newOJN wrappers are now supported. Across the three reference
installations this brings 494 charts into range that could not previously
be opened at all. - No sample-package work was needed: every
new-wrapped chart pairs with an
M30, OMC, or OJM package that was already supported. The encryption is on the
chart container only.

Verification
All 958 charts across three retail installations now parse, up from 464 in
1.0.0, and 957 of them render. The single exception is one chart whose sample
package carries header counts that disagree with the other 951 packages in the
corpus; it is rejected deliberately rather than accepted on the strength of a
lone specimen.
Every one of the 494 new wrappers decrypts to a valid ordinary OJN across the
eight block sizes those files use. Decryption was also checked against an
independent reimplementation, which reproduced the renderer's output to the
exact sample on both a plain decrypted chart and the hardest case in the corpus
(decryption combined with 15 measure fractions and mid-measure tempo changes).
Also covered by 829 test assertions, libFuzzer smoke runs on both parsers with
seeds for the new decryption paths, and a clean ASan/UBSan pass in the
glibc-2.17 release container. The o2ma100 reference render is byte-identical
to 1.0.0, confirming ordinary charts are unaffected.
macOS and the Windows x86 legacy build remain untested -- presets exist, but
no machine was available to build or verify them.
