v1.0.2: codebase refactor and performance tweaks

2024-09-09 v.1.0.2

• performance: optional caching of tags in a project's .micro/cache directory, useful on Android Termux and with tojour.potatomode (configurable with tojour.cache and tojour.cache_dir options)
• refactor: splits Lua codebase into separate files for Tests, TJSession, TJPanes, FileLink, TJConfig, Common (thanks MicroOmni sourcecode for help in getting 'require' to finally work)
• refactor: reformats all Lua files with StyLua code formatter.
• performance: Unit testing Tests.lua lib is now only required if env variable TOJOUR_DEVMODE=true
