Updates unicode-display_width from 2.6.0 to 3.1.2

Changelog

Sourced from unicode-display_width's changelog.

3.1.2

• Performance improvements

3.1.1

• Performance improvements

3.1.0

Improve Emoji support:

• Emoji modes: Differentiate between well-formed Emoji (:possible) and any ZWJ/modifier sequence (:all). The latter is more common and more efficient to implement.
• Unify :rgi_{fqe,mqe,uqe} options to just :rgi to keep things simpler (corresponds to the former :rgi_uqe option). Most terminals that want to support the RGI set will probably want to catch Emoji sequences with missing VS16s.
• Add new :all_no_vs16 and :rgi_at modes to be able to support some terminals that needs these quirks
• Add alias emoji: :auto for emoji: true and emoji: :none for emoji: false
• :auto mode: Only consider terminal cells when recommending Emoji support level (Emoji themselves might display differently)
• :auto mode: Set default Emoji mode for unknown/unsupported terminals to :none
• Rename :basic mode to :vs16

3.0.1

• Add WezTerm and foot as good Emoji terminals

3.0.0

Rework Emoji support:

• Emoji widths are now enabled by default
• Only reduce Emoji width to 2 when RGI Emoji detected (configurable)
• VS16 turns Emoji characters of width 1 into full-width
• Please note that Emoji parsing has a notable impact on performance. You can use the emoji: false option to disable Emoji adjustments
• Tries to detect terminal's Emoji support level automatically (from ENV vars)

Index fixes and updates:

• Private-use characters are considered ambiguous (were given width 1 before)
• Fix that a few zero-width ignorable codepoints from recent Unicode were missing
• Consider the following separators to be zero-width:
  • U+2028 - LINE SEPARATOR - Zl
  • U+2029 - PARAGRAPH SEPARATOR - Zp

Looks like unicode-display_width is no longer updatable, so this is no longer needed.
