Update vt100 requirement from 0.15.1 to 0.16.1

[dependabot]

Updates the requirements on vt100 to permit the latest version.

Changelog

Sourced from vt100's changelog.

[0.16.1] - 2025-07-10

Changed

• Reverted to the 2021 edition for now.

[0.16.0] - 2025-07-08

Added

• Parser::process_cb, which works the same as Parser::process except that it calls callbacks during parsing when it finds a terminal escape which is potentially useful but not something that affects the screen itself.
• Support for xterm window resize request escape codes, via the new callback mechanism.
• Support for dim formatting. (Daniel Faust, #9)
• Support for CNL/CPL escape codes. (Danny Weinberg, #10)
• Support for OSC 52 (clipboard manipulation).

Removed

• These methods on Screen have been removed in favor of the new callback API described above:
  • title_formatted
  • title_diff
  • title
  • icon_name
  • bells_diff
  • audible_bell_count
  • visual_bell_count
  • errors
• Additionally, unhandled escape sequences no longer log to STDERR; they instead call various callback methods which can be defined to log if desired.
• Cell no longer implements Default.
• Screen no longer implements vte::Perform.

Changed

• Parser::set_size and Parser::set_scrollback have been moved to methods on Screen, and Parser::screen_mut was added to get a mutable reference to the screen.
• Cell::contents now returns &str instead of String, eliminating an allocation in many cases. (Chris Olszewski, #14)

Fixed

• Fixed some issues with calculating scrollback offsets correctly in Grid::visible_rows. (rezigned, #11)
