CRAM now requires .bai index, just like BAM.
Test updates:
- Updated existing MD5s, as TLEN has changed.
- Tests multiple contigs.
- Tests several intervals per contig.
- Tests when `.cram.bai` is missing, even when `.cram.crai` is present.
Updated gatk docs for CRAM support, including:
- Arguments that work for both BAM and CRAM listed as such.
- Arguments that don't work for CRAM either explicitly say "BAM" or "doesn't work for CRAM".
- Instructions on how to recreate a `.cram.bai` using cramtools.
Cleaned up IntelliJ IDEA warnings regarding `Arrays.asList()` -> `Collections.singletonList()`.
