For loops support a range syntax for iterating a fixed number of times,
which looks like this.
```liquid
{% for i in range (1..100) %}
...
{% endfor %}
```
Previously, we converted these ranges to arrays using `to_a`, which
initialized an array containing each number in the range. Since all we
use these ranges for is iteration, this is far less efficient than
using a range iterator.
Doing this means that iterating over ranges now takes O(1) rather than O(n)
memory. See the PR for more benchmarks.
* Remove to_a cast on ranges
* Add ReversableRange iterator
* Add custom range-specific slicing logic
