Sample signal and push to ringbuffer
When filled, send buffer to queue
Process queue with FFT
Append to results Vec

- Sample signal and push to [ringbuffer](https://lib.rs/crates/ringbuffer) - When filled, send buffer to [queue](https://lib.rs/crates/crossbeam-queue) - Process queue with [FFT](https://lib.rs/crates/microfft) - Append to results `Vec`

Random test data is pushed into buffer
Filled buffer is inserted into queue
Queue has test action performed on it

Due to issues with libraries, just a simple array is used for the buffer, and tinyvec is used for the queue.

Embassy Channel is now being used as a queue, and greatly simplifies it.
Data still needs to be processed.

Data is now processed to find a power spectrum (using example code), and should work as described by this Thinking Cap tutorial?

Again, must be tested to actually know for sure.
Additionally, I'm not sure if a low-pass filter or Hanning window needs to be used with the library.
Similarly, interrupts or something will likely need to be used in order to ensure sampling happens at a reliable rate.
