string2path 0.2.0

• Partially support COLRv1 emoji fonts.

  • COLRv1 emoji font is a color emoji, but not all color emoji is COLRv1
    format. For example, Noto Color Emoji has several variants, and it seems
    the primary one is CBDT/CBLC format.
  • Additional information are currently just discarded.
    • The clip and layer composition information are just discarded. While
      this can be useful, it's not very easy to use these information in R.

• Fix string2fill() and string2stroke(); when the second argument is a path
  to a file, these unintentionally worked as string2path().

• string2path() now generates the same outline as string2fill() and
  string2stroke() (#69).

• path_id and glyph_id are now 1-origin.

• The result of string2fill() and string2stroke() now don't contain a
  path_id column. I found the calculation of path_id had never been
  correct, and it's probably better to remove it to avoid confusion.
