Added disc type and manufacturer lookup from ATIP. * DiscImageChef.Decoders/CD/PMA.cs: Implement full PMA decoding. * DiscImageChef.Decoders/CD/FullTOC.cs: Implement decoding disc ID. * DiscImageChef.Decoders/SCSI/MMC/DiscInformation.cs: Disc ID is 24-bit. * DiscImageChef.Decoders/CD/CDTextOnLeadIn.cs: CD-TEXT can be empty without being null, do not decode an empty one.
