Bug: Unable to write data via influxdb-writer

[VeddySama]

What were you trying to achieve?

In the latest SuperMQ code implementation, the process of retrieving SenML-formatted data from NATS incorporates timestamp conversion to nanosecond precision. However, the InfluxDB writer component exhibits incompatibility with nanosecond-granularity timestamps. The specific code artifacts responsible for this discrepancy are identified at:

1. supermq/pkg/transformers/senml/transformer.go:70
   (Nanosecond conversion logic for SenML timestamps)

2. supermq-contrib/consumers/writers/influxdb/consumer.go:131
   (InfluxDB timestamp ingestion handler)

What are the expected results?

Write data correctly

What are the received results?

Unable to write data

Steps To Reproduce

No response

In what environment did you encounter the issue?

In the latest code

@VeddySama InfluxDB writer needs to sync with the recently released v0.17.0 of the core services. It's low on our current priority list, but all PRs and help are welcome.
