Feature: allow test name customisation when using parameters via | operator

[lgrossi]

Expected Behavior

When using parametrization with | operator would be nice to be able to give each test a unique identifier, to make spot of issues easier and to avoid weird behaviors. E.g. when using parametrization with | the number of assertions is way higher than the same set of tests using for();

Actual Behavior

When comparing different ways of adding test parameters, we have:

suite<"more assertions"> a = [] {
	test("MyTest") = [](auto fixture) {
		expect(fixture > 0);
		expect(false);
	} | std::vector{1,2,3,4};
};

suite<"less assertions"> b = [] {
	for(auto fixture : std::vector{1,2,3,4}) {
        test("MyTest" + std::to_string(fixture)) = [&fixture]() {
			expect(fixture > 0);
            expect(false);
        };
    }
};

The first way, using | has two problems: it doesn't allow test name customisation, leaving to warnings during failures, and it creates way more assertions than the second approach.

Ideally would be nice that both ways have a consistent behavior and that no extra assertions get generated in the print.
