fix(transform): Change Kinesis Payload Limit to MB

[jshlbrd]

Description

• Changes the payload size limit for Kinesis Data Streams from MiB to MB

Motivation and Context

Discovered an edge case where the system generated a Kinesis Data Stream payload of more than 5 MB when using the PutRecords API. Changing the limit of each record from 1 MiB (1048576 bytes) to 1 MB (1000000 bytes) fixed the problem. According to the AWS docs, Firehose uses 1 MiB as its message size limit.

How Has This Been Tested?

Tested E2E in the production data pipeline the bug was discovered in.
