ugrep: updated to 7.0.3

ugrep v7.0.3

make Windows ugrep.exe TUI cursor keys behave with ConEmu
fix Windows ugrep.exe TUI CTRL-Y file viewing for non-ASCII filenames
minor usability improvements suggested by ugrep users. Thank you for your feedback!

ugrep v7.0.2

Fix ugrep v7 regression bug: an issue with the regex ^ anchor due to a \ 
misaligned begin-of-line position in the buffer after the buffer shifts on large \ 
input files. As a result, the -v option did not always work properly on large \ 
input files when searching with regex ^ anchors. Reverted to the old logic. \ 
Included a minor change to handle hex context lines

ugrep v7.0

rewritten SIMD acceleration logic and the search algorithm selection decision \ 
logic to speed up pattern matching (the actual speedup depends on the type of \ 
regex patterns specified)
improved regex anchors and word boundary matching speed and support
fix option --xml pathnames with special characters, which are unlikely to occur \ 
in pathnames, but aren't strictly forbidden
updated option --hexdump with -ABC context hex lines before and after a match
the TUI now also uses the VISUAL environment variable if PAGER is not set
