SingleFile CLI 2.15.7

CLI fixes and improvements

Browsers installed for the current user are now found without --browser-executable-path: in %LOCALAPPDATA% on Windows (Chrome, Chrome Canary, Brave, Vivaldi, Opera, Yandex, Firefox), in ~/Applications on macOS, and via snap and the PATH on Linux
Firefox installed from the Microsoft Store (or with winget install Mozilla.Firefox.MSIX) is now found on Windows
The "browser executable was not found" error is now reported in 1 second instead of about 60 seconds on Windows
On Windows, --browser-single-process is now applied to Google Chrome only. Edge, Brave, Vivaldi, Chromium and Chrome for Testing exit in this mode, so each run relaunched the browser. It saves about 5 seconds per run, and about 65 seconds with Edge
Vivaldi can now be used. It did not answer any command sent to a new tab until the tab was navigated, so the page setup never ended (simple-cdp is updated to 1.10.2)
The capture now fails with a timeout when the browser stops answering during the page setup, instead of hanging
With Firefox, the CLI now waits for the browser to exit before removing its temporary profile
The README explains how to use the Flatpak version of Firefox
