Deocde Error on Long type when message is in Avro.

[yonathan-shtekel]

Hey guys,
For Avro messages when message contain Long type the decode is failing.
I'm not a javascript professional but there is a different between long type in Avro and bigInt in javascript and maybe need to create a new logicalType that make this conversion.

any way this is the error:
[2023-09-06 23:11:19.376] ERROR: [KAFKA]: {"timestamp":"2023-09-06T20:11:19.376Z","logger":"kafkajs","message":"Error when calling eachMessage","topic":"some-topic-name","partition":21,"offset":"14","stack":"Error: potential precision loss\n at LongType._read (/Users/yonathan.shtekel/Riskified/helpers/loadmill-kafka-relay/node_modules/avsc/lib/types.js:918:11)\n at RecordType.readEventMetaData [as _read] (eval at RecordType._createReader (/Users/yonathan.shtekel/Riskified/helpers/loadmill-kafka-relay/node_modules/avsc/lib/types.js:2296:10), <anonymous>:5:8)\n at RecordType.readLinkingFeaturesExtractionEvent [as _read] (eval at RecordType._createReader (/Users/yonathan.shtekel/Riskified/helpers/loadmill-kafka-relay/node_modules/avsc/lib/types.js:2296:10), <anonymous>:5:8)\n at readValue (/Users/yonathan.shtekel/Riskified/helpers/loadmill-kafka-relay/node_modules/avsc/lib/types.js:2914:17)\n at RecordType.Type.fromBuffer (/Users/yonathan.shtekel/Riskified/helpers/loadmill-kafka-relay/node_modules/avsc/lib/types.js:601:13)\n at SchemaRegistry.decode (/Users/yonathan.shtekel/Riskified/helpers/loadmill-kafka-relay/node_modules/@kafkajs/confluent-schema-registry/src/SchemaRegistry.ts:331:25)\n at processTicksAndRejections (node:internal/process/task_queues:95:5)","error":{}}

way to reproduce:
Create a scheme with long type property and produce and consume the message from topic.
This is happening at the subscribe end point, when the service is actually consuming the messages.
