Fix UTF-16BE text decoding for song titles and file paths

[MarlonS91]

Summary

Fixes UTF-16BE text decoding in Serato library files and updates Jest test infrastructure to v25.

Changes

🐛 Fix: Correct UTF-16BE text decoding in 'tsng' and 'pfil' chunks

Problem:
The parser was using latin1 encoding for all text chunks by default, which failed to properly decode UTF-16BE encoded text in Serato library files. This caused emojis and special characters in song titles and file paths to display incorrectly.

Solution:
Added specific parsing logic for tsng (Song Title) and pfil (File Path) chunks:

• Swap bytes to convert from big-endian to little-endian format
• Decode as UTF-16LE to match Serato's encoding format

case "tsng":
case "pfil":
  data = buffer.slice(index + 8, index + 8 + length).swap16().toString('utf16le');
  break;

⬆️ Chore: Update Jest dependencies and test configuration

Dependency Updates:

• @types/jest: 24.9.1 → 25.1.0
• ts-jest: 24.3.0 → 25.2.0

Configuration Improvements:

• Enhanced test regex: "(/tests/.*|(\\.|/)(test|spec))\\.(jsx?|tsx?)$"
  • Matches both /tests/ directory and .test./.spec. naming conventions
• Added testPathIgnorePatterns: ["/node_modules/", "/lib/"]
  • Excludes build artifacts and dependencies from test runs

📦 Chore: Bump version to 1.3.2

Updated package version to reflect the bug fix and dependency updates.

Testing

• Verify UTF-16BE text decoding with Serato files containing emojis
• Confirm all existing tests pass with updated Jest configuration
