deps: update mammoth requirement from >=1.12.1 to >=1.13.0

[dependabot]

Updates the requirements on mammoth to permit the latest version.

Changelog

Sourced from mammoth's changelog.

1.13.0

• Read the children of w:customXml elements.

• Handle paragraphs and runs that have been moved and tracked as a revision.

• Improve escaping in Markdown writer. This avoids some cases where source documents could inject arbitrary HTML into the converted document.

1.12.2

• Avoid excessive backtracking when parsing an unterminated string with many escape sequences. The previous behaviour would allow maliciously crafted documents to cause a denial of service.

  Note that it is still strongly recommended to process untrusted documents in a separate thread with a timeout to avoid potential similar issues.

• Handle complex field separator and end characters without corresponding start characters.

1.12.1

• Fix: on Windows, when an image's content type includes a backslash in the subpart, files may be written outside of the directory set by --output-dir.

• Detect and ignore numbering levels that use numStyleLink to refer to themselves.

1.12.0

• Handle hyperlinked wp:anchor and wp:inline elements.

• Handle hyperlink complex fields with unquoted hrefs.

1.11.0

• Ignore style definitions using a style ID that has already been used.

• Fix conversion of unmerged table cells.

• Disable external file accesses by default. External file access can be enabled using the external_file_access argument.

• Handle numbering levels defined without an index.

1.10.0

• Add "Heading" and "Body" styles, as found in documents created by Apple Pages, to the default style map.
