Remove empty "object" variable from payload.js

[Freddyminu]

Decoder Description

Adding removal of the empty "object" key. An empty object key is generated by the toTagoFormat function whenever chirpstack sends a multi leveled json of decoded data from their CODEC.

Added the removal of the object key if its value is empty since this causes connectors to fail.

Type of change

• Adding a new Decoder of Connector
• Adding a new Decoder of Network
• Update or fixing an issue in existing Decoder

Decoder Information and Payload to test and review

• Documentation of the hardware or protocol:
• Payload of example the test the decoder:

Checklist for Adding a New Decoder

• Created a new folder under ./decoders/network/ or ./decoders/connector/ with the name of your decoder.
• Added a network.jsonc or connector.jsonc file that follows the structure defined in ./schema/.
• Created version folders and added manifest.jsonc files for each version.
• Followed the folder structure guidelines for manufacturer and sensor/device model.
• The code has unit test and it's in TypeScript.

Additional Notes

Please add any other information that you think is important.

It looks like object can be sent as customized payload from Chirpstack.

I'd rather prefer to parse the Object parameter with the toTagoFormat,

  if (chirpstack_payload.object) {
    vars_to_tago = vars_to_tago.concat(toTagoFormat(chirpstack_payload.object, serie));
    delete chirpstack_payload.object;
  }

Also, as you're updating this connector, also ensure to update the "serie" to "group"
