azb:// URI does not work well with vcf2genomicsdb_init in GenomicsDB

[nalinigans]

Not sure I am constructing the URI correctly. But the following does not work

% ./vcf2genomicsdb_init -w ws -o -S azb://<container>/vcfs
[E::hts_open_format] Failed to open file "azb://<container>/vcfs/t0.vcf.gz" : Protocol not supported
16:54:14.024 ERROR vcf2genomicsdb_init - pid=10937 tid=6368523 Could not open sample azb://<container>/vcfs/t0.vcf.gz with hts_open Protocol not supported
% ./vcf2genomicsdb_init -w ws -o -S azb://nalini/vcfs?endpoint=<account>.blob.core.windows.net

whereas this works!

% ./vcf2genomicsdb_init -w ws -o -S az://<container>@<account>.blob.core.windows.net/vcfs
