v1.24.0

Changes since 1.23.0:

- Report the paint each text run was shown with: `TextItem` gains `fill_color` and `stroke_color` (8-bit sRGB, read from DeviceRGB, DeviceGray, DeviceCMYK, ICCBased by component count and Indexed palettes; `None` for Separation, DeviceN, Pattern and CIE-based spaces) and `render_mode` (the `Tr` mode, so invisible text and clipping-only text can be told apart). Extraction and markdown are unchanged (#579).
- Read the document information dictionary's `/Author`, `/Subject`, `/Keywords`, `/Creator`, `/Producer`, `/CreationDate` and `/ModDate` beside `/Title`, each decoded as a PDF text string (#579).
- Decode the document `/Title` as a PDF text string: titles in PDFDocEncoding no longer read with U+FFFD, titles in UTF-16LE no longer read as mojibake, and titles given by reference are read (#579).
- Extract text a page shows with the `"` operator, which the page parser skipped together with the spacing and line move it makes (#579).
- Take an ActualText span's weight from the paint of its first painted glyph rather than from the paint in force at the span's end (#579).
- Keep two lines of small type apart when their baselines lie less than 5 pt apart: a stacked table header at 4.7 pt on a 4.5 pt pitch no longer comes out as words zipped from both lines, and type of 8⅓ pt and above groups exactly as before (#580).

API: `TextItem::fill_color`, `stroke_color` and `render_mode` (Node `fillColor`, `strokeColor`, `renderMode`; Python `fill_color`, `stroke_color`, `render_mode`; the `pdf2md --items-json` fields), and the `PdfProcessResult` / `PdfTypeResult` fields `author`, `subject`, `keywords`, `creator`, `producer`, `creation_date` and `mod_date` (Node and WebAssembly in camelCase, Python as attributes, and the `pdf2md --json` / `detect-pdf --json` members). Rust literals of these types must include the new fields.

Release preparation: #582.
