Support Y-axis and X-axis "breaks" when `annotate=TRUE`

[trevorld]

Currently:

library("ppcli")
library("ppdf")
> cat_piece(marble_board(nrows = 5), annotate = T)
10─────────┐
9│◌ ◌ ◌ ◌ ◌│
8│         │
7│◌ ◌ ◌ ◌ ◌│
6│         │
5│◌ ◌ ◌ ◌ ◌│
4│         │
3│◌ ◌ ◌ ◌ ◌│
2│         │
1│◌ ◌ ◌ ◌ ◌│
 └─────────┘

but it could be nice if we could suppress those final axis labels (that don't refer to where a piece can go but the edge of the board):

> cat_piece(marble_board(nrows = 5), annotate = T, breaks = 1:9)
 ┌─────────┐
