Nightly 20220427 - More stable, WAV player, audio battery test

This release is a big step forwards, as the stability has been increased dramatically. I can now debug the Hackiebox CFW via SWD. I am also using the same compiler as for the Hackiebox NG Bootloader. The building / debugging isn't included, as there are still some things to do, to make it work for everybody. Also using the new compiler breaks WiFi, as it need additional delays and won't work after a soft reset / hibernation)

• WAV audio player will now play all files in a folder, in copy order (not by name!). Please resample to 32k mono
• Static memory management for the audio player (stability)
• Battery test now includes audio playback, to make it more realistic (and faster).
• RFID detection is a bit slow now (you may switch two tags very fast now)
• Dynamic ears-sounds, depending on the sample rate (not perfect for non-standard sample rates beside 16k)
• Update WiFi Server (ESP32 as base)
• Added memory canaries
• Several optimizations to reduce compiler warnings and small bugs
• Red LED can be disabled in favour of SWD

The tapping to jump to the next / previous songs doesn't work, as there is still an issue with the detection.

Don't forget to copy over the audio files for the battery test! The audio pack contains free songs preconverted to 16k mono.

To compile it yourself, please also update your Energia toniebox-cc3200-core!
