mupdf: update to 1.24.0.

List of changes in MuPDF 1.24

	Error handling changes:

		You must call pdf_report_error in the final fz_catch. Any
		unreported errors will be automatically reported when a new
		error is raised, or when closing the fitz context.

	New formats:

		Read Office (XML) files! We internally open and convert
		docx/pptx/xlsx documents to HTML to allow reading the plain
		text content. The exact layout will NOT be preserved.

		Optional compile time option to use libarchive for reading CBR
		and other archive formats.

		Read plain text documents.

		Read gzipped files directly.

		Open and read FDF files to support importing annotations or
		form data using the low-level PDF functions. There are no tools
		for this yet.

		Read CFB (Compound File Binary) format archives -- used for the
		Office formats.

		Write images as JPEG2000.

	New tools and features:

		mutool bake (and associated functions) to bake appearance of
		annotations and forms into static content.

		Font subsetting flag to mutool clean (EXPERIMENTAL FEATURE).

		Option to use ObjStms when writing PDF files.

		Compression effort option when writing PDF files.

		Add option to control how line art is affected by redaction.
		Add more options to control how images are affected by
		redaction (remove-unless-invisible).

		Fix up q/Q gstate balance when cleaning content streams.

	New functions and types:

		pdf_rearrange_pages to subset or re-order pages in a PDF file.

		fz_invert_bitmap to invert monochrome bitmaps.

		fz_compressed_image_type to query the format of a compressed
		image.

		fz_text_decoder to convert various legacy and CJK encodings
		into UTF-8.

		More helper functions to easily manipulate PDF objects in C.

		Add flag to control fz_place_story overflow behavior when the
		text doesn't fit into the box.

		New archive handlers can be added at runtime.

	Major bug fixes and improvements:

		Support using Art, Bleed, Media, and Trim boxes for PDF page
		size.

		Support ActualText in PDF! No more strange text extraction when
		the file uses ActualText to patch over bad font encodings.

		Add special TrueType fallback encoding CMap for a specific
		flavor of broken PDF files that use an "identity" encoding
		without embedding the font.

		Limited "transfer function" support in PDF. Transfer functions
		are a deprecated legacy PDF feature that predates proper color
		management. They were intended to provide limited color
		management such as applying a gamma curve. Transfer functions
		have often been (ab)-used to invert images, and many PDF
		creators use them when writing softmask images. We have added
		support for this case only.

		Box drawing characters added to fonts for HTML and plain text
		documents.

		Write more compact PDF files (removed some unneccessary
		whitespace).

		Improved selection behavior for non-axis aligned text.

		Improved heuristics for detecting the logical and visual order
		of RTL text in PDF.

		Improved heuristics for inserting missing spaces in PDF text.

		Improved handling of CMYK JPEG files (which ones are inverted
		and which are not).

		Improved content type detection. Don't assume everything is PDF
		when we can't recognize it.

	Removed deprecated functions:
		pdf_check_signature
