CandleStickChart auto scaling min/max is not working correctly

* [x] I've read, understood, and done my best to follow the [*CONTRIBUTING guidelines](https://github.com/jjatie/Charts/blob/master/CONTRIBUTING.md).

## What did you do?

CandleStickChart auto scaling min/max is not working correctly.

## What did you expect to happen?

If `isAutoScalingMinMaxEnabled` was `true`, we can see entire values from min `shadowL` to max `shadowH` of visible entries.

## What happened instead?

We can only some part of values.


## DGCharts Environment

**DGCharts version/Branch/Commit Number:**
**Xcode version:** 15.0.1
**Swift version:** 5
**Platform(s) running DGCharts:** iOS
**macOS version running Xcode:** 14.3.1（23D60）

## Demo Project

https://github.com/mithril1992/ChartsBugReproduction

Start with the CandleStickChart auto-scaling behavior and the linked ChartsBugReproduction demo project. Inspect how visible entries determine the shadowL and shadowH range when isAutoScalingMinMaxEnabled is true; done means the full visible range is shown on iOS, from the minimum shadowL to the maximum shadowH.
