Customizable test pyramid graph in allure 3

Currently, test pyramid graph is having only 3 supported values in layer like e2e, integration, unit. It would be great if we can add some customizable values which can be supported like manual, performance etc.

const chartsConfig = defaultChartsConfig.map((chart) =>
chart.type === "testingPyramid"
? { ...chart, layers: ["manual", "integration", "e2e"] }
: chart
);

Secondly, the order of that is fixed like unit at the bottom, integration and e2e at the top. Can this be rendered based on the number of tests it has for each layer.
In the picture I don't have unit tests so I expect that section to be gone as well and I can have my own customized layer for that.

Start by locating the testingPyramid chart and defaultChartsConfig, then trace how the chart's layers and test counts are assembled. Done means callers can provide custom layer names and ordering, and layers with no tests are omitted from the rendered graph.
