ugrep: updated to 4.3.0

ugrep v4.3.0

Redesigned TUI with a new split screen window pane to preview matching files.

new TUI split screen, activated with CTRL-T, and new option --split to start the \ 
TUI with a split screen (add split to your .ugrep configuration file to enable)
improved TUI screen updating
refactored the search engine internals to keep the search engine alive until \ 
ugrep terminates to optimize the TUI matching file preview pane display speed
improved option -o (--only-matching) layout when context options -ABC are used
fixed --zmax=n for n>1 that had a low chance to hang as discovered recently \ 
(about once in a few thousand runs) when searching (deeply) nested zip or tar \ 
archives
fixed compressed file search of files that are exactly one byte long, instead of \ 
rejecting those files as being empty
updated performance benchmark results: ugrep is faster than other grep tools on \ 
x64 and arm64 machines in nearly every test of 564 benchmark test cases
