standardlastprofile 1.1.0

New profiles

• Added five new standard load profiles published by BDEW in 2025: H25
  (household), G25 (commerce), L25 (agriculture), P25 (combination
  profile with photovoltaics), and S25 (combination profile with storage and
  photovoltaics). All five are available via slp_generate() and slp_info(),
  and are included in the slp dataset.

New features

• slp_generate() gains a holidays argument: a character or Date vector of
  ISO 8601 dates that are treated as public holidays (mapped to "sunday" in
  the algorithm). When supplied, the built-in holiday data are ignored entirely,
  giving callers full control over which dates count as holidays.

Deprecations

• The state_code argument of slp_generate() is deprecated. Pass a vector
  of holiday dates to the new holidays argument instead (#3).

Bug fixes

• Fixed incorrect weekday assignment when a date range contains a Dec 24 or
  Dec 31 that falls on a Sunday. The previous check used all() across the
  entire range, which caused every other Dec 24/31 in the range to be mapped to
  "workday" instead of "saturday" (#2).
