- Update to version 1.4.0:
  - ERFA 1.4.0 adds the eraVersion and eraSofaVersion functions to
    determine the installed version of ERFA (and the SOFA version
    it is derived from).
  - ERFA 1.4.0 includes some bug fixes contributed to ERFA after
    1.3.0 but before 1.4.0. These were incorporated (with
    modification) into SOFA "20170420" (without attribution) and
    hence these are not differences between ERFA and SOFA
    (gh#liberfa/erfa#40, gh#liberfa/erfa#41).
