Migrate to standard OS config location if ~/.hyperhdr folder is missing

[awawa-dev]

If default ~/.hyperhdr folder does not exists, create it and propose it as default in the default OS location and use it - otherwise use standard ~/.hyperhdr directory as a base for HyperHDR user data storage.

Default OS locations:

Platform	Example Path (HyperHDR)
Linux	~/.config/HyperHDR
macOS	~/Library/Preferences/HyperHDR
Windows	C:\Users\<User>\AppData\Local\HyperHDR

Resolves #1425

I think it should have been this:

If ~/.hyperhdr folder already exists, use it as a base for HyperHDR user data storage, otherwise create and use the default OS location.

Thank you for this!

Yeah, I actually overcomplicated it (in terms of translation) and it came out completely messy/chaotic.
But since we went all-in anyway, soon HyperHDR with the installers will also become compliant with the Linux Filesystem Hierarchy Standard after merging PR #1477
