Properly handle incorrect CLI arguments in tt-smi

[hmohiuddinTT]

Tried to run tt-rmi -r with multiple device ids but the program crashed. Should do some argparsing and fail gracefully with a cleaner error message.

Looks like there is a device id 8 doesn't exist on the pci bus. Could you remove it and try again?
But, I will also add a cleaner exit when the device isn't found - to make it easier for user to debug

Oh yeah I didn't even realize I added an extra device, but yeah we should still handle it gracefully.

more try/except blocks! ;-)

This isn't an easy fix on the Python side, since Rust panics aren't thrown as regular Exceptions in pyO3, but rather inherit from BaseException. We can catch the BaseException but it'll still print the Rust panic and could cause issues with safety. This needs to be changed on the Luwen side to throw an error rather than panic.
