Remarks
Not copy constructable, not assignable.
BGZF is the Block GZip Format which is used as the underlying format for BAM and TABIX.
Data is written out compressed with gzip but the uncompressed data is split into blocks with a maximum block size.
It is therefore possible to jump to beginnings of blocks in the resulting files, decompress the block and then jump into the block itself.
