Update compilation guide

[Rugikex]

This PR fixes a compilation issue with newer scripts using 'zoneinfo'.
It also updates the 'Compile to executable' section in the README to match the clear, OS-separated instructions found in iLEAPP.

Hi, I noticed the files have been updated since then. Is this PR still needed, or should I close it?

Thanks for checking back @Rugikex, and sorry for the slow reply! 🙏 Here's where things stand — it's a split answer:

The zoneinfo part is no longer needed. It has since landed on main and is now present in all six spec files (including the _Linux and _macOS ones that didn't exist when you opened this). That's also why the PR is showing conflicts.

The README part is still very much wanted — arguably more than when you opened it. What's on main today is wrong: it tells people to run pyinstaller --onefile aleapp.spec, but there's no aleapp.spec at the repo root anymore (they all moved to scripts/pyinstaller/), and we've since added OS-specific specs the README says nothing about. So anyone following it hits a wall. Your OS-separated layout is exactly the right fix, and dropping --onefile/--noconsole is correct too since the specs already set those themselves.

If you're up for rebasing on current main and keeping just the README change, three small things to fix:

1. Drop the leading separator — \scripts\pyinstaller\aleapp.spec and /scripts/pyinstaller/... are absolute paths from the drive/filesystem root. They should be relative: scripts\pyinstaller\aleapp.spec / scripts/pyinstaller/aleapp_macOS.spec.
2. Filename casing — the actual files are aleapp_macOS.spec and aleappGUI_macOS.spec (capital OS). aleapp_macos.spec happens to work on macOS's case-insensitive default but breaks on case-sensitive setups.
3. Add Linux — we now ship aleapp_Linux.spec and aleappGUI_Linux.spec, so a Linux section alongside Windows and macOS would round it out.

No rush at all, and if you'd rather not bother with the rebase just say the word and we'll pick it up from here with credit to you. Either way, thanks for spotting the zoneinfo crash and for circling back on this. 🚀

I have updated the README according to your feedback. Let me know if everything looks good now!
Just a heads up: Ileapp's README was updated in the meantime, but I kept the older version here.
