• Changed "NNW" to "up-left" etc. Compass directions still work, but the built-in dataset purpose has different names and documentation will gradually change to the new terms.
• Patches for upcoming upstream changes

unpivotr 0.5.0

New features

• behead_if() is for tiered headers within the same row or column. It takes filter functions similarly to dplyr::filter() to decide which cells to treat as headers, and can be applied more than once to the same row or column of headers until every tier has been dealt with.
• merge_rows() and merge_cols() combines header text when it is split over multiple cells.

Other changes

• behead(), enhead(), partition() and rectify() give a more informative error message for non-distinct cells, for example when trying to pass cells from more than one sheet to these functions (@gregrs-uk, #15).

Tiny bugfix release to pass tests on all CRAN platforms.

• Made compatible with tidyxl version 1.0.0 (avoids dplyr::distinct(), which doesn't handle list columns).
• Updated to use the new dplyr/rlang combination instead of the old dplyr/lazyeval one.
