  \_lv_svg_tokenizer [#_lv_svg_tokenizer]

  Parse SVG data and call a callback for each token.

  | Name        | Type                                 | Description                                       |
  | ----------- | ------------------------------------ | ------------------------------------------------- |
  | `svg_data`  | `const char *`                       | pointer to SVG data                               |
  | `len`       | <ApiLink name="uint32_t" />          | length of the SVG data                            |
  | `cb`        | <ApiLink name="svg_token_process" /> | callback function to be called for each token     |
