H: Horizontal sampling factor – Specifies the relationship between the component horizontal dimension
and maximum image dimension X (see Jpeg Spec A.1.1); also specifies the number of horizontal data units of component
Ci in each MCU, when more than one component is encoded in a scan.
Vi: Vertical sampling factor – Specifies the relationship between the component vertical dimension and
maximum image dimension Y (see Jpeg Spec A.1.1); also specifies the number of vertical data units of component Ci in
each MCU, when more than one component is encoded in a scan.
Tqi: Implied from the position in parsing
