textproc/hgrep: update to 0.1.8

-syntect-printer supports text-wrapping. Longer lines than terminal width are
now wrapped by default. It can handle wide characters including special emojis
with zero-width joiner (U+200D)
-syntect-printer highlights matched regions in matched lines with a searched
text color. Since match positions in matched lines are not included in output
from grep -nH, currently this is only supported by combination of
syntect-printer feature and ripgrep feature
-syntect-printer now uses light dashed lines for the separator of snippets
-Add --wrap MODE option where MODE is one of char or never (the default value
is char). More modes may be implemented in the future
-In favor of --wrap option, --no-wrap flag is now deprecated and will be
removed at v0.2.0. Use --wrap never instead
-When building binaries for Windows, link C runtime statically. This avoid
depending on vcruntime DLL at runtime
-Critical section of syntect-printer was optimized. It slightly improved
performance (around 4% faster in benchmarks)
-Enable thin LTO for release build. It slightly improved performance
(0~6% faster in benchmarks)
