7zip compressor issue with v10.0.22

[amaulave]

Hello,

Following fix on issue #49 I downloaded 10.0.22 release and unfortunately I still have an error when I tried to extract the archive with py7zr:

$ py7zr x Collect_Full_DESKTOP-S3MCBR3_20211202_181230_System.7z out
Traceback (most recent call last):
  File "/usr/local/bin/py7zr", line 8, in <module>

$ py7zr t Collect_Full_DESKTOP-S3MCBR3_20211202_181230_System.7z

Bad 7zip file

If I uncompress then recompress the archive using 7-Zip tool without modification to files, the new archive can be proceed without issues:

$ py7zr t Collect_Full_DESKTOP-S3MCBR3_20211202_181230_System_repaired.7z
Testing archive: Collect_Full_DESKTOP-S3MCBR3_20211202_181230_System_repaired.7z

Type = 7z
Phisical Size = 173337431
Headers Size = 1004
Method = LZMA2
Solid = +
Blocks = 1

Everything is Ok


$ py7zr x Collect_Full_DESKTOP-S3MCBR3_20211202_181230_System_repaired.7z out2
$ echo $?
0

This is published with 10.0.23, I hope it will fix your issues with py7z. I tested with multiple archives using Ubuntu 20.04, py7zr 0.17.2, Python 3.8.10.
