Adding rotation based on branch feat/rotate

[TID-Test]

To make it easier when using raspberry pi touch display 2, could we add the rotate argument?

Can you add a test similar to this one here?

flutterpi_tool/test/commands/devices_test.dart

Lines 752 to 783 in 3b33866

	test('meta-flutter', () async {
	var addDeviceWasCalled = false;
	config
	..addDeviceFn = (entry) {
	expect(
	entry,
	src.DeviceConfigEntry(
	id: 'test-device',
	sshExecutable: null,
	sshRemote: 'test-device',
	remoteInstallPath: null,
	filesystemLayout: FilesystemLayout.metaFlutter,
	),
	);
	addDeviceWasCalled = true;
	}
	..containsDeviceFn = (id) {
	return false;
	};
	await _runInTestContext(() async {
	await runner.run(
	['devices', 'add', 'test-device', '--fs-layout=meta-flutter'],
	);
	});
	expect(
	addDeviceWasCalled,
	isTrue,
	reason: 'addDeviceFn should have been called',
	);
	});

one test case each for 0, 90, 180 and 270, and one for e.g. 179 and an expect() that it errors in that case.

@TID-Test "build test app" failing is not important, just a GH rate limit. Though flutter build workflow says there's a trailing comma missing somewhere
