zipfile39

Backport of zipfile Python 3.9 (especially caae717) to older Python including Python 2.7.
- This means Python 2.7 can use zf.open(name, 'w').
Uses backports.lzma for ZIP_LZMA (method 14) Python2 handler.
Introduces ZIP_DEFLATED64 (method 9), ZIP_DCLIMPLODED (method 10), ZIP_ZSTANDARD(method 93), ZIP_XZ (method 95) and ZIP_PPMD (method 98) handlers.
- ZIP_ZSTANDARD Python2 uses zstandard 0.14.1 (the last compatible version).
- isal / pyppmd / zipfile_deflate64 Python2 use my own backport.
If isal is installed:
- crc32 and inflation are accelerated automatically.
- ZIP_DEFLATED compresslevel -10, -11, -12 and -13 are available, which correspond to isal compression level 0, 1, 2 and 3.
If slz is installed:
- ZIP_DEFLATED compresslevel -21 is available.
If codecs7z is installed:
- ZIP_DEFLATED/ZIP_BZIP2 compresslevel 11 - 19 are available. Enjoy 7-zip's ultimate compression on Python.

Test requisites:
- All optional requisites

Some dependencies need complex build procedures. For your sake those wheels are published in actions CI.

I'm not sure about the license term when pyppmd / codecs7z / inflate64 is loaded (I'm not lawyer though).
- For pyppmd, note that PPMd code itself is public domain. See https://github.com/miurahr/pyppmd/issues/5#issuecomment-892280467 for detail.
