Permission Denied when executing extracted executable file from Tar #424

@adamhathcock commented on GitHub (Nov 3, 2020):

That's likely because your executable file you made main does not have permissions to execute. Nothing to do with sharpcompress

I search it a little more and saw that Sharcompress alters the permissions on a file

This is the executable outputted by the compiler

This is the executable after compression and decompression

I don't think Sharpcompress does the right thing in setting or preserving the permissions of a file

@adamhathcock is there any configuration for me to remove this, this configuration kind of messed up all my program configuration

Also Something that doesn't make any sense:
when I unpack the windows app version the permission is leaved as default:

Here is what I did

On linux, mac and FreeBSD(I believe, I have to check this info thought) the executable doesn' t have an extension, so I check for this and just give the file permission, But i would be cool If It can do it automatically
