NSZ 2.1 Changelog:

• 98 commits worth of changes since v2.0
• Added pip support
• Added Nuitka standalone windows build support
• Enhanced File Existing Check #20
  • Skip already compressed/decompressed files by default
  • --overwrite
  • --rm-old-version
  • Extracting TitleIDs and Versions from filename if possible (#17 and #19)
    • The titleID checking is now immensely faster than when extracting from Cnmt
  • --parseCnmt to get TitleID/version from Cnmt if not extractable from filename
    • Otherwise it falls back to simple filename checking which is much faster
• Batch error handling with tracebacks (#16)
  • Some debugging codes to find out erroneous files
  • Prevent batch process raising errors
  • Batch error handling with tracebacks
• The --thread option now works even for solid compression however the progress bar still has some visual glitches
• NSP/NSZ file hash verification now uses the hashes inside Cnmt instead of the nca filename (#22)
• Fixed decompression memory leak (#21)
  • The memory leak only occurs for dctx.stream_reader and was fixed by switching to the simple decompressing API which makes more sense for block decompression anyways
• Improved pageReadSize calculation speed by using math instead of a while loop
• Added option --remove-source that deletes the source file after compression or decompression (#24)
  • For this we finally properly closed file containers too
• Fix huge compression memory leak (#13)

• Improved exception handling during TitleID/Version extraction
  • Added support for prod.keys
• Reorganized file structure

• Fixed default thread amount to be cpu_count()

  • Compatible and tested with Python 3.6 and later
• General system stability improvements to enhance the user's experience.
