v0.6.2

Fixed

• ADIF is read by qso_graph_lib.adif, the fleet's one ADI reader, which reads ADI as
  ADIF 3.1.7 defines it and passes ADIF's own test files. This server's scanner read a
  Header's fields as the first QSO's, so ADIF_VER and PROGRAMID (with trailing spaces)
  reached tool results in that QSO's adif fields, and a length that ran past the next tag
  returned two QSOs as one. New dependency: qso-graph-lib>=0.2.0 (standard library only).
