Bump RangeExtensions from 1.2.2 to 2.0.0

[dependabot]

Bumps RangeExtensions from 1.2.2 to 2.0.0.

Release notes

Sourced from RangeExtensions's releases.

2.0.0

Changes

✨ New Features

Select and Where

This release expands the list of Range extensions with several convenience methods that bring it much closer to counterparts in Rust, Python and others.

var floats = (0..100).Select(i => (float)i);
var odd = (0..100).Where(i => i % 2 != 0);
var randomNumbers = (0..1000)
.Select(_ => Random.Shared.Next())
.ToArray();

Iterating through these directly is significantly faster when compared to Enumerable.Range. In fact, with DynamicPGO enabled, on osx-arm64 the loop foreach (var i in (0..1000).Select(i => i * 2)) gets within 1.3-1.5x ratio of a regular plain for loop. Delegate devirtualization has gotten so good!

IList on RangeEnumerable and SelectRange

Now both these types also implement IList. While RangeEnumerable is effectively a materialized sequence of numbers, SelectRange serves a purpose of "Select View" over that sequence, with exact T values materialized on access similar to plain IEnumerable<T>.

While this does not conform 100% to existing semantics, it was a necessary change to take the advantage of IEnumerable internals for methods that lack bespoke implementations in this library or when RangeExtensions enumerators are boxed.

Bespoke Aggregate, First, Last and more

The library now exposes additional bespoke LINQ method implementations for shorthand usage together with Range that further improve its usability in functional scenarios.

var digits = (0..10)
    .Aggregate(new StringBuilder(), (sb, i) => sb.Append(i))
    .ToString();
Assert.Equal("0123456789", digits);
// None of these allocate, and all of them are O(1)
var fifteenthDecimal = (0..1337)
.Select(i => (decimal)i)
.Take(10)
.ElementAt(4); // or even just [4]
// Efficient scan from the end of the range
var lastEven = (0..1337)
.Where(i => i % 2 is 0)
.Last();

... (truncated)
