@abstract Structure for core alignment information.
@field tid chromosome ID, defined by bam_header_t
@field pos 0-based leftmost coordinate
- @field strand strand; 0 for forward and 1 otherwise
@field bin bin calculated by bam_reg2bin()
@field qual mapping quality
@field l_qname length of the query name
@field l_aux length of auxiliary data
@field data_len current length of bam1_t::data
@field m_data maximum length of bam1_t::data
- @field data all variable-length data, concatenated; structure: cigar-qname-seq-qual-aux
+ @field data all variable-length data, concatenated; structure: qname-cigar-seq-qual-aux
@discussion Notes:
1. qname is zero tailing and core.l_qname includes the tailing '\0'.
2. l_qseq is calculated from the total length of an alignment block
on reading or from CIGAR.
+ 3. cigar data is encoded 4 bytes per CIGAR operation.
+ 4. seq is nybble-encoded according to bam_nt16_table.
