/**
 * Sorting markers in rows from left to right. Because geolocation can be pretty
 * detailed we can't just sort it as is, we need a math to make it feel natural.
 *
 * How this works:
 * - Prioritise sorting on latitude (y-axis)
 *   - multiply the difference and round it this will "group" locations in rows.
 *   - 30 is an arbitrary value that felt good in my case, higher values will make tighter rows.
 *   - (Using `1` as multiplier you will see the sorting jumps long distances from left to right.)
 * - If 0 (same row), sort by longitude, with full precision
