Support PPMd; Fix Zstd and Append Mode

Changed

• PPMd: Use stream encoder/decoder instead of buffered one.
• PPMd: Use ppmd-cffi@v0.3.1 and later.(#268)

Added

• PPMd compression/decompression support.(#255)
• New API to set methods to set header encode mode, encode or encrypted.(#259)
• Support Python 3.9.(#261)
• Support arm64/aarch64 architecture on Linux.(#262)

Fixed

• Append mode cause error when target archive use LZMA2+BCJ.(#266)
• Fix zstandard compression/decompression.(#258)

Deprecated

• Drop support for python 3.5 which become end-of-life in Sept. 2020.

Fix header error when larger archive extraction

Fixed

• Fix exception when reading header which size is larger than buffer size (#252)
  A bug affected from v0.10.0a1 to v0.10.0

Support "Append" mode

The version 0.10.0 and its pre-released versions have a critical known bug on header parsing.
You are strongly recommended to use v0.10.1 and later, or v0.9.9.

Changes from v0.9.2

Fixed

• Fix BCJ(x86) filter code with a missing logic which cause extraction error
  for certain data. (#249, #250)
• Raise PasswordRequired when encrypted header without passing password (#234, #237)
• CLI: don't raise exception when password is wrong or not given.(#229)
• Fix specification typo.
• Catch exception in threading extraction(#218,#219)

Added

• Compatibility test with python-libarchive-c/libarchive for compression(#247)
• Document: express how to handle multi-volume archive (#243)
• SevenZipFile.needs_password() method.(#208, #235)
• CLI: Support append mode command line.(#228)
• Support "APPEND" mode. User can open SevenZipFile() class with mode='a' (#227)

Changed

• Calculate CRC32 of header without re-reading header from disk again.(#245)
• read(), extract(): improve performance when specifying parts of archived file,
  by skipping rest of arcvhive when target file has extracted.(#239,#242)
• read(), extract(): improve performance when specifying parts of archived file,
  by not running threads for unused compression blocks(folders).(#239,#242)
• docs: improve API documentation.(#244)
• setup: set minimum required python version as >=3.5
• Compression will be happened when call write() not close() (#222, #226)
