Decompress 7-ZIP file with password

What steps did you take?

func TestOpenReaderWithPassword(t *testing.T) {
	t.Parallel()

	tables := []struct {
		name, file, password string
	}{
		{
			name:     "xxxx header compression",
			file:     "7zcracker.7z",
			password: "876",
		},
	}
....

see: reader_test.go
the file url: download
the file is created by "7z2201-x64.exe" （from www.7-zip.org） with default options.

What did you expect to happen, and what actually happened instead?

After my testing:

All 7-zip encrypted files created by software 7-zip (official windows x64 version, default options) cannot be decrypted.

but files encrypted by another software Bandzip can be decrypted normally.
