python3-cbor2: upgrade 5.7.1 -> 5.8.0

Contains fix for CVE-2025-68131

Changelog:
- Added readahead buffering to C decoder for improved performance.
  The decoder now uses a 4 KB buffer by default to reduce the number
  of read calls. Benchmarks show 20-140% performance improvements for
  decoding operations.
- Fixed Python decoder not preserving share index when decoding array
  items containing nested shareable tags, causing shared references to
  resolve to wrong objects
- Reset shared reference state at the start of each top-level encode/decode
  operation

Ptests passed:
...
PASS: tests/test_tool.py:test_dtypes_from_file
PASS: tests/test_tool.py:test_ignore_tag
PASS: tests/test_types.py:test_frozendict
