Public API and backward incompatible changes

New RasterImageLoadOptions

To enable conversions from HEIC images, the following NuGet package must be referenced: FileFormat.HEIC.
Use the code snippet below to perform the conversion:

public class HeicConnector : IHeicConnector
{
    public BitmapInfo GetBitmapInfo(Stream heicStream)
    {
        var heicImage = HeicImage.Load(heicStream);
        var pixels = heicImage.GetByteArray(FileFormat.Heic.Decoder.PixelFormat.Bgra32);
        var width = (int)heicImage.Width;
        var height = (int)heicImage.Height;
        return BitmapInfo.Create(pixels, width, height, BitmapInfo.PixelFormat.Bgra32);
    }
}

var loadOptions = new RasterImageLoadOptions();
loadOptions.SetHeicConnector(new HeicConnector());

FluentConverter.Load("sample.heic")
    .WithOptions(loadOptions)
    .ConvertTo("sample.heic.png")
    .WithOptions(new ImageConvertOptions { Format = ImageFileType.Png })
    .Convert();

A new property, Encoding has been added to SpreadsheetConvertOptions. This property allows you to specify the encoding to be used when converting to delimited formats.
