ugrep v4.5.0

What's new?

• 7zip archive search with option -z #185
• apply Unicode normalization to canonicalize literal combining characters in regex patterns #298
• improved TUI TAB directory navigation when searching from the FS root
• updated ugrep.exe option -P to use PCRE2 latest stable version 10.42

Future plans (work in progress)

• implement a new DFA-based regex search optimization for patterns described in #288
• speed improvements for Linux with io_uring (could be 2x faster)
• update ugrep benchmarks when some or all speed improvements are included (no update yet, because v4.5.0 is as fast as the current benchmarks show)
