It is not possible to set 'smlAutoChildTableNameDelimiter' nor 'smlChildTableName' when trying to insert schemaless OpenTSDBJsonFormatProtocol using the nodeJs connector

[patmcquade]

Bug Description
When setting smlAutoChildTableNameDelimiter to any value and then trying to insert schemaless data using the InfluxDB Line Protocol via the @tdengine/websocket node package, it results in an error. Using smlChildTableName has no effect, and the table names are the same as when omitting to set this value.

All of the above works when using InfluxDB Line Protocol instead of OpenTSDB JSON protocol but i actually would prefer using the OpenTSDB JSON protocol

I'm using the kubernetes Deployment from https://docs.tdengine.com/operation/deployment/#kubernetes. This has a few problems to start when using as described with tdengine 3.3.3.0 which i could resolve. I had to replace the taoskeeper.toml and set the TAOS_ADAPTER_NODE_EXPORTER_URLS env variable as both had at buildkitsandbox somewhere instead of 127.0.0.1.

To Reproduce
Steps to reproduce the behavior:

1. set smlAutoChildTableNameDelimiter to any value i tried it with '_'
2. run the example https://docs.tdengine.com/reference/connectors/node/#schemaless-writing removing/commenting out the telnet and influxparts
3. The creation of the db works but writing the data fails

---

1. set smlChildTableName to 'tname'
2. run the example https://docs.tdengine.com/reference/connectors/node/#schemaless-writing removing/commenting out the telnet and influxparts and edit the influxdata var to
   let jsonData = ["{\"metric\": \"metric_json\",\"tname\":\"some_tname\",\"timestamp\": 1626846400,\"value\": 10.3, \"tags\": {\"groupid\": 2, \"location\": \"California.SanFrancisco\", \"id\": \"d1001\"}}"];
3. the generated table does not have the name some_tname as defined above but the autogenerated name

Expected Behavior
It should work as described in the documentation https://docs.tdengine.com/reference/schemaless/#main-processing-logic-for-schemaless-writing, which is the case with the InfluxDB Line Protocol
