Rework config and reload config on file change/creation/deletion (#663) * add config.py and config_event_handler.py also introduces the utils folder * update config imports and variables * add 'pyinotify' dependency * config: check for changes using threading * config: handle errors and new eventsx * config: set_path even if file doesn't exist and make new ConfigParser on every update * fix get_config call * config: check for changes on moved file * call notifier.start() manually to prevent hanging * config: update comments * battery: fix config imports * config: fix config deletion detection * Add load from user config in XDG_CONFIG_HOME if available (#672) * Add load from user config from in XDG_CONFIG_HOME if available This update introduces the flexibility to load the configuration file from multiple locations, prioritizing user preferences and system standards. Previously, the configuration was strictly read from a hardcoded system path (`/etc/auto-cpufreq.conf`). Now, the application first checks if the user has specified a configuration file path via command line arguments. If not, it looks for a configuration file in the user's config directory (`$XDG_CONFIG_HOME/auto-cpufreq/auto-cpufreq.conf`). If neither is found, it defaults to the original system-wide configuration file. This allows users to add their auto-cpufreq configuration to their dotfiles. * If --config is set but invalid, exit with error * Remove redundant empty string check on config file path * Remove duplicate isfile check for config path See also: https://github.com/AdnanHodzic/auto-cpufreq/pull/672#discussion_r1548003119 * Update configuration options in README See also: #672 * config: move find_config_file function and fix finding home directory * auto_cpufreq: fix hanging on --daemon, --live, and --monitor * swap pyinotify for patched version --------- Co-authored-by: Steven Braun <steven.braun.mz@gmail.com>
