Implements Unicode Standard Annex #29 grapheme cluster boundaries. Handles Hangul syllables, emoji ZWJ sequences, regional indicators, combining characters, and Indic scripts. New exports: iter_graphemes, _bisearch
We suggested to use ``wcwidth<2`` for years, when it should have been ``wcwidth<1``, I really hope somebody didn't copy & paste our recommendation .. :(
its a private function, anyway, still ok. Below the turtles, 0/1 is very much the definition of Falsey and Truthy.

- Add new `width()` function for measuring terminal-aware strings, with support for control codes, escape sequences (SGR, OSC, CSI), cursor movement, and tab stops. - Add `iter_sequences()` function to iterate with text containing escape sequences - New file, `control_codes.py` for control characters, categorized - New file `escape_sequences.py` for terminal sequence patterns, categorized - extract `_bisearch` , duplicates #165 A few examples from docs/intro.rst: >>> wcwidth.width('\x1b[38;2;255;150;100mWARN\x1b[0m') 4 >>> list(wcwidth.iter_sequences('\x1b[31mred\x1b[0m')) [('\x1b[31m', True), ('red', False), ('\x1b[0m', True)] >>> wcwidth.width('\U0001F1FF\U0001F1FC') 2

New ``wrap()`` function is an emoji, control and terminal sequence, wide, zero-width, and grapheme-aware version of textwrap.wrap(). This PR builds on #168 and #165 combined >>> # Wrapping CJK text (each character is 2 cells wide) >>> wrap('コンニチハ', 4) ['コン', 'ニチ', 'ハ'] >>> # Text with ANSI color sequences >>> wrap('\x1b[31mhello world\x1b[0m', 5) ['\x1b[31mhello', 'world\x1b[0m']

iter_graphemes()function for Unicode grapheme cluster iteration following UAX #29. Enables segmentation of "user-perceived" characters: emoji sequences, combining marks, regional indicators, Indic conjuncts.A few examples from docs/intro.rst:
