native: Try to look for a config file based on Raspberry Pi HAT vendor

[Stary2001]

This should make it so you can add new hats (and USB devices!) without adding entries to the configProducts map, only by adding a new config file with the correct name based on the programmed vendor/product.

Pull Request Overview

This PR enhances the LoRa device auto-configuration functionality by adding support for dynamic config file generation for unknown devices and improving HAT vendor detection. The changes refactor error handling from exception-based to condition-based logic while adding the ability to generate configuration filenames based on device vendor and product information.

• Added cleanupNameForAutoconf function to sanitize device names for config filenames
• Enhanced HAT detection to capture and display vendor information alongside product names
• Replaced exception-based config lookup with conditional logic and fallback config generation

On my RPi5 (trixie) I don't have a folder /proc/device-tree/hat, but one called hat_type2:

$ ls -la /proc/device-tree/hat_type2/

I'll be getting a hat+ in the next couple days, and can compare notes then.

On a Zero 2 with trixie, I have it:

stary@fixer:~ $ ls /proc/device-tree/hat
custom_0  name  product  product_id  product_ver  uuid  vendor
stary@fixer:~ $

Is that Pi 5 specific?
