Too verbose by default (virtual_hid_keyboard_ready)

[codyadam]

Running karabiner_driverkit::grab() is causing excessive console spamming.

Once we run grab(), the lines bellow are called every 100 milliseconds, resulting in a significant amount of console spam. It would be beneficial to default to a less verbose logging level.

Reference:

driverkit/c_src/driverkit.cpp

Lines 107 to 110 in 655422f

	client->virtual_hid_keyboard_ready.connect([](auto&& ready) {
	std::cout << "virtual_hid_keyboard_ready " << ready << std::endl;
	sink_ready.store(ready, std::memory_order_release);
	});

Console output:

virtual_hid_keyboard_ready true
virtual_hid_keyboard_ready true
