Add support to setup List<CoverletOutputFormat>

CoverletOutputFormats = new List<CoverletOutputFormat> {
CoverletOutputFormat.opencover,
CoverletOutputFormat.covertura
};

Hi there,

You can support multiple coverlet formats by providing them like this:

var coveletSettings = new CoverletSettings {
        CollectCoverage = true,
        CoverletOutputFormat = CoverletOutputFormat.opencover | CoverletOutputFormat.covertura,
        CoverletOutputDirectory = Directory(@".\coverage-results\"),
        CoverletOutputName = $"results-{DateTime.UtcNow:dd-MM-yyyy-HH-mm-ss-FFF}"
    };

Or by using the method on the settings class like this:

var coveletSettings = new CoverletSettings {
        CollectCoverage = true,
        CoverletOutputFormat = CoverletOutputFormat.opencover,
        CoverletOutputDirectory = Directory(@".\coverage-results\"),
        CoverletOutputName = $"results-{DateTime.UtcNow:dd-MM-yyyy-HH-mm-ss-FFF}"
    }.WithFormat(CoverletOutputFormat.covertura);

I'll use this issue as a note to improve the documentation in the readme. Thanks

This does not work for us. How about providing a placeholder (like %format%) in the CoverletOutputName that is automatically replaced with the defined format.
So we could use:

CoverletOutputName = $"{projectName}-%format%.xml"

to generate xxx-opencover.xml and xxx-cobertura.xml and we would not need to rely on timestamps anymore.
