Support for arrays in `startsWith` (and, maybe, `endsWith`)

**Use case**

Would be quite useful for handling tree-like structured data where the node paths are specified as arrays of names or IDs.

**Describe the solution you'd like**

The desired behavior would be like this:
```
startsWith([1, 2, 3, 4], [1, 2])  -- true (1)
startsWith(['qwe', 'rty', 'ui', 'op'], ['qwe', 'rty'])  -- true (1)
startsWith([1, 2, 3, 4], [2, 4])  -- false (0)
startsWith([1, 1, 2, 2], [1, 2])  -- false (0)
```

And similarly, for `endsWith`

**Describe alternatives you've considered**

Something like `arraySlice(first, 1, length(second)) = second`

But `startsWith` would be much more readable, harder to make a mistake in and, probably, can be better optimized (i.e. might not have to create new objects like `arraySlice` does)
{
    sink.reserve(std::max(src_a.getSizeForReserve(), src_b.getSizeForReserve()));
    const UInt8 * cond_pos = condition.data();
    const UInt8 * cond_end = cond_pos + condition.size();
    bool a_is_short = src_a.getColumnSize() < condition.size();
    bool b_is_short = src_b.getColumnSize() < condition.size();
    while (cond_pos < cond_end)
    {
        if (*cond_pos)
            writeSlice(src_a.getWhole(), sink);
        else
            writeSlice(src_b.getWhole(), sink);
        if (!a_is_short || *cond_pos)
            src_a.next();
        if (!b_is_short || !*cond_pos)
            src_b.next();
        ++cond_pos;
        sink.next();
    }
