Fixed support for CVC concatenated signatures
Created by: rvillido
This change fixes support for CVC concatenated signatures (in addition to ASN.1 encoded signatures).
This fix is related to the ticket DSS-801 and a previous pull request (https://esig-dss.atlassian.net/browse/DSS-801 and https://github.com/esig/dss/pull/36).
The previous pull request was not sufficient to cover all CVC concatenated signatures. We found that some still caused problems so we had to change ASN1StreamParser to ASN1InputStream in determining if it's a CVC or ASN1 signature.
