ZIP_CHECKCONS wrong failures with stored, encrypted entries - fix included

[ralfjunker]

ZIP_CHECKCONS reports wrong failures for stored, encrypted entries.

This happens because encryption adds extra bytes to the compressed size which zip_dirent_check_consistency() (GIT main at the time of this writing) does not take into account.

Here is a proposed fix:

int
zip_dirent_check_consistency(zip_dirent_t *dirent) {
    if (dirent->comp_method == ZIP_CM_STORE)
        switch (dirent->encryption_method) {
            case ZIP_EM_NONE:
                if (dirent->comp_size != dirent->uncomp_size)
                    return ZIP_ER_DETAIL_STORED_SIZE_MISMATCH;
                    break;
            case ZIP_EM_TRAD_PKWARE:
                if (dirent->comp_size != dirent->uncomp_size + 12)
                    return ZIP_ER_DETAIL_STORED_SIZE_MISMATCH;
                    break;
            case ZIP_EM_AES_128:
                if (dirent->comp_size != dirent->uncomp_size + 20)
                    return ZIP_ER_DETAIL_STORED_SIZE_MISMATCH;
                    break;
            case ZIP_EM_AES_192:
                if (dirent->comp_size != dirent->uncomp_size + 24)
                    return ZIP_ER_DETAIL_STORED_SIZE_MISMATCH;
                    break;
            case ZIP_EM_AES_256:
                if (dirent->comp_size != dirent->uncomp_size + 28)
                    return ZIP_ER_DETAIL_STORED_SIZE_MISMATCH;
                    break;
        }
    return 0;
}

Applied, thanks.
