[dependabot]

Bumps mammoth from 1.12.2 to 1.12.3.

Changelog

Sourced from mammoth's changelog.

1.12.3

• 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.
