feat: advanced matchers with post-process option

[NoamGaash]

apply post-proccessing on the chosen HAR entry:

test("get the largest number... squared!", async ({ page, advancedRouteFromHAR }) => {
	// the file contains 3 responses - 42, 1234, 5
	await advancedRouteFromHAR("tests/har/differentNumbers.har", {
		matcher: {
			postProcess(entry) {
				entry.response.content.text = (parseInt(entry.response.content.text || "0") ** 2).toString();
				return entry;
			},
			matchFunction: customMatcher({
				scoring: (request, entry) => parseInt(entry.response.content.text || "0"),
			}),
		}
	});
	await page.goto("https://noam-gaash.co.il");
	await page.getByText((1234**2).toString()).waitFor();
});
