ppcli 0.3.0 (development)

cat_piece() and str_piece() adds support for the following game pieces (#4):
- "cubes" bit pieces
- (piecepack) saucers

ppcli 0.2.1

cat_piece() and str_piece() adds support for the following game pieces (#4):
- "alquerque" bit and board pieces.
- "dice_numeral" dice.
- "marbles" bit and board pieces.
  - However we currently do not distinguish between the nine marble bit ranks.
- "morris" bit and board pieces.
- "reversi" bit and board pieces.
cat_piece() and str_piece() gain arguments xbreaks and ybreaks to provide a subset (of integers) to provide axis labels for if annotate is TRUE (#17).
cat_piece() and str_piece() now supports the "cyan" and "magenta" colors (#5).

"white" go and marbles bits should now render the same whether piece_side is "bit_back" or "bit_face".
checkers1 and checkers2 bit faces should now render as checker "kings". Bit backs should continue to render as checker "men".
cat_piece() and str_piece() now expand the drawing range for longer (piecepack) matchsticks if necessary (#14).
str_piece()'s color argument if NULL now falls back to FALSE (instead of throwing an error).
Should now be able to correctly rotate chess knights 315 degrees.

cat_piece() prints out Unicode plaintext boardgame diagrams.
- It supports the same data frame arguments also supported by piecepackr::pmap_piece() / piecepackr::render_piece() as well as the board game setup functions in {ppdf}.
- It is an extraction and refinement of ppgames::cat_piece().
str_piece() computes the character vector of Unicode plaintext boardgame diagrams (#1).
