[FL-1472, FL-1596, FL-1673] IRDA: stability improvements (#655)

- Restrict with 31 bytes length for remote and signal name
- Don't stuck for 0 PWM cycle timings
- Support timings > 65535 PWM cycles
- Fix remote file open error
- Add IRDA TX debug redirect
- Add remote parse error print, improve parsing, support tabs
- Fix stucks with uncorrect RAW signal values, long strings in remote file, etc
- Fix HAL signals capturing (save previous read value)
- Fix leak in case of failed parsing
