In EPS/PostScript, `0#7` asked i64::from_str_radix for radix 0, which panics (found by
fuzzing). Radixes outside 2..=36 are not numbers now.

The s, b and b* operators closed the path even when there was no current point, which kurbo
asserts against (a panic in debug builds; found by fuzzing). Close only when a subpath is open.
CFF charstrings that draw before their first rmoveto now start the subpath at the current
point, as Type 1 charstrings already did. Denies the panic lints in the crate (it had no panic
sites).
