[Feature request]: Allow specifying the physical device for Vulkan

[ilkecan]

Please describe your feature request

What do you think about adding an option to specify the physical device for Vulkan? I have two on my system and the first one doesn't have the required extensions, so Vulkan can't initialize. It works fine if I change the code to use the second one.

wluma/src/frame/vulkan.rs

Lines 55 to 58 in 0c49755

	let physical_devices = unsafe { instance.enumerate_physical_devices()? };
	let physical_device = *physical_devices
	.get(0)
	.ok_or("Unable to find a physical device")?;

Thanks, truth be told I cut corners, hardcoded 0 and was waiting until someone asked for this, as I don't have a way to test it 😁

The correct approach is to query device capabilities and select the best device that supports everything we need.

Some examples:

• inspiration / general concept
• ash code example, probably we need something very similar

If you would like to experiment and make a PR, let me know, it's very appreciated!

I will look into this. Thanks for the pointers.
