hms 0.4.0

Breaking changes

• as.hms.POSIXt() now defaults to the current time zone, the previous default was "UTC" and can be restored by calling pkgconfig::set_config("hms::default_tz", "UTC").

New features

• Pillar support, will display hms columns in tibbles in color on terminals
  that support it (#43).
• New round_hms() and trunc_hms() for rounding or truncating to a given multiple of seconds (#31).
• New parse_hms() and parse_hm() to parse strings in "HH:MM:SS" and "HH:MM" formats (#30).
• as.hms.POSIXt() gains tz argument, default "UTC" (#28).
• as.hms.character() and parse_hms() accept fractional seconds (#33).

Bug fixes

• hms() now works correctly if all four components (days, hours, minutes, seconds) are passed (#49).
• hms() creates a zero-length object of class hms that prints as "hms()".
• hms(integer()) and as.hms(integer()) both work and are identical to hms().
• Values with durations of over 10000 hours are now printed correctly (#48).
• c() now returns a hms (#41, @qgeissmann).

Documentation and error messages

• Fix and enhance examples in ?hms.
• Documentation is in Markdown format now.
• Improved error message if calling hms() with a character argument (#29).
