Completely revamp the grab source code

Some of the (many) few changes are:
- Multithreading for significantly faster performance
- The -p/--predicate flag
- Byte offsets as the default
- No customizable colors (maybe this will come back later)
- Newer edition of mlib (formerly librune)

-.Fn u8len "const char8_t *s" "size_t n"
-.Sh DESCRIPTION
-The
-.Fn u8len
-function returns the number of UTF-8 encoded Unicode codepoints in the
-buffer
-.Fa s
-of length
-.Fa n
-bytes.
-.Pp
-This function assumes that
-.Fa s
-contains only valid UTF-8.
-.Sh RETURN VALUES
-The
-.Fn u8len
-function returns the number of codepoints in the buffer
-.Fa s .
-.Sh EXAMPLES
-The following call to
-.Fn u8len
-will return 17 while the call to
-.Fn strlen
-will return 22 as a result of use of multibyte-characters in
-.Fa s .

-.Sh CAVEATS
-The return value of
-.Fn u8len
-does not necessarily represent the number of human-preceived characters
-in the given buffer;
-multiple codepoints may combine to form one human-preceived character
-that spans a single column.
-To count user-preceived codepoints
-.Pq also known as graphemes ,
-you may want to use the
-.Xr u8glen 3
-function.
