TODOs

• Fine-tune tempo calculation
• Experiment with two more calculations:
  • Measure from start tapping until last tap (A-Z / T)
  • Measure taps intervals and analyze the BPM based on a mean frequence. (Based on a standard deviation?)
    • Function std
• Add an accuracy bar. Bottom window. From L->R >> from Red to Green. From about 50 taps is Green-isch, which means pretty accurate.
• Add Typescript types
