Hi, I just ran into an issue with picard (3.4.0) . I have a CRAM file for a large genome. This is why it does not have a CRAI index, but a CSI index. Unfortunately, it dies with the message `CRAM index must be a BAI or CRAI stream` (see https://github.com/samtools/htsjdk/blob/master/src/main/java/htsjdk/samtools/CRAMFileReader.java#L208) Would it be possible to enable/allow CRAMs with CSI indices, too? Thank you!
