Per official Sensirion driver, check data ready status before
attempting to read number concentration values.

Use the same pattern as main measurement read instead of
get_register. This separates the write and read with an
explicit delay.

Instead of reading NC immediately after main measurements,
alternate between them on each update cycle. This gives the
sensor more time between I2C transactions and avoids bus
contention issues.

- Increase delay between main measurement and NC read to 200ms
- Increase get_register delay to 50ms
- Add debug logging for NC values

Per SEN6x datasheet: sensor needs 100ms after power-on before
I2C communication can be started.

- Use get_register() with proper delay instead of separate write/read
- Only attempt NC read if NC sensors are configured
- Increase timeout between measurement reads
- Change error level to warning (non-critical feature)

- Move initial I2C check outside of timeout for immediate failure detection
- Add proper error codes for all failure cases
- Improve dump_config to show specific error messages
- Add more debug logging during initialization
