v2.7.0

The new Profile Editor was coded with Codex. It uses ImGui to render the window and widgets. Check out the README for more info on how to use it.

Changes:

• Updated the README with notes about the new Profile Editor app
• Updated the build and install process to include the Profile Editor
• Added Doxygen docs to g13_device
• Added helper to trim command tails for profile and reload_profile, so FIFO commands pass a clean GUID instead of raw whitespace/newline text
• Changed profile switching to use profile GUID/id, ignore empty profile switch requests, and lazily load {profiles_dir}/{id}.xml if that profile is not already loaded
• Changed profile switch logging to include both profile name and GUID
• Changed load_profile() to replace the loaded profile object directly and update _current_profile if the reloaded GUID is currently active
• Changed reload_profile(id) to try loading the XML file even if the profile is not already in _profiles, and to log a warning if the file does not exist
• Added a first attempt at a Profile Editor GUI
