Spectrum analyser code is not compatible with latest firmware

[lokedhs]

I fixed the code so that it compiles with the latest framework. You can find my patch here: https://codeberg.org/loke/flipperzero-firmware/commit/bd3058d75f4d7d9e7ab39388ce99e87093048555

This runs with the latest filpperzero-firmware as of today.

Is this a direct copy with the addition of the application.fam file or are there other code changes? I'm deciding if I should replace the link with this one or Unleashed's modifications.

It is a direct copy that is fixed to use the new flipperzero API's. I later noticed that this was already included in the unleashed firmware, so there isn't really a need for my port.
