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)

- * Simple & stupid dynamic array single-header implementation.  You can use the
- * macros defined in this file with any structure that has the following fields:
- *
- *  struct dyn_array {
- *      T *buf  // Array of items
- *      N  len  // Length of array
- *      N  cap  // Capacity of array
- *  }
- *
- * The type ‘T’ is whatever type you want to store.  The type ‘N’ is any numeric
- * type — most likely ‘size_t’ — but it could be sized as well.
- *
- * The daremove() macro also doesn’t bother with shrinking your array when the
- * length is far lower than the capacity.  If you care about that, do it
- * yourself.
- *
- * Remember to call free() on your dynamic arrays ‘buf’ field after use.
- *
- *
- * Macro Overview
- * ――――――――――――――
- * The argument ‘a’ to all of the below macros is a pointer to the dynamic array
- * structure.
- *
- * dainit(a, n)              Initialize the array with a capacity of ‘n’ items.
- * dapush(a, x)              Append the item ‘x’ to the array
- * daremove(a, x)            Remove the item at index ‘x’ from the array
- * da_remove_range(a, x, y)  Remove the items between the range [x, y)
- * da_foreach(a, p)          Iterate the pointer ‘p’ over each element of the
- *                           array.  The type of ‘p’ is inferred.
- *
- * The ‘dapush()’ macro will double the arrays capacity when it gets full.  If
- * you would like your arrays to grow with a different scale, edit this file.
- *
- *
- * Example
- * ―――――――
- *
- * struct {
- *     int *buf;
- *     size_t len, cap;
- * } nums;
- *
- * // Initialize nums with capacity == 4
- * dainit(&nums, 4);
- *
- * // Append 69, 1337, and 420 to nums
- * dapush(&nums, 69);
- * dapush(&nums, 1337);
- * dapush(&nums, 420);
- *
- * da_foreach (&nums, n) {
- *     int x = *n << 1;
- *     printf("n = %d; n² = %d\n", *n, x);
- * }
- *
- * // Remove 1337 and 420 from nums
- * da_remove_range(&nums, 1, 3);
- *
- * // Remove 69 from nums
- * daremove(&nums, 0);
