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)

-.Ft size_t
-.Fn u8gnext "struct u8view *v" "const char8_t **s" "size_t *n"
-.Sh DESCRIPTION
-The
-.Fn u8gnext
-function stores a view of the first grapheme in the buffer
-.Fa s
-of length
-.Fa n
-in the structure pointed to by
-.Fa v .
-It then updates
-.Fa s
-to point to the next grapheme in the buffer and also updates
-.Fa n
-accordingly.
-.Pp
-The
-.Vt "struct u8view"
-type is described in the
-.Xr u8view 3
-manual.
-.Sh RETURN VALUES
-The
-.Fn u8gnext
-function returns the length of the grapheme iterated over in bytes,
-or 0 at the end of iteration.
-.Sh EXAMPLES
-The following calls to
-.Fn u8gnext
-iterate over and print all the graphemes in
-.Va s .
-.Bd -literal -offset indent
-#define STRING u8"नमस्कार विश्व"
-
-struct u8view v;
-const char8_t *s = STRING;
-size_t n = sizeof(STRING) - 1;
-
-while (u8gnext(&v, &s, &n))
-	printf("‘%.*s’\en", (int)g.len, g.p);
