lightr 1.6.0

Major breaking changes

• The date returned in metadata (by lr_get_metadata(),
  lr_convert_tocsv(metadata = TRUE) and lr_parse_XXXX()) is now a datetime
  (with UTC as timezone and format %Y-%m-%d %H:%M:%S).
  The column name in lr_get_metadata() has been updated from date to
  datetime to reflect this. Thanks to Giancarlo Chiarenza for the report, and
  to Hao Ye, Laura DeCicco and Elin Waring for helpful comments about timezones
  and datetime formatting for reproducibility.

Minor changes

• datetime parsing is supported for more formats
• Files produced by OceanInsight software (such as SpectraSuite) in Spanish
  can now be parsed)
