fix(decoder): use configurable limit for max number of records in a record batch#3120
Conversation
created `getArrayLengthNoLimit` as record batches can contain more than `2*math.MaxUint16 records`. The packet decoder will make sure that the array length isn't greater than the number of bytes remaining to be decoding in the packet. Also added a test for large record counts.

Not sure how useful making this parameterizable is, when the CRC will change if the value changes, but then I like that it’s apparent and inarguable what length we’re encoding.

Yea I only set it as a var to make it obvious what it is. I kept forgetting what I had it set to during testing, so it's probably useful just to have it easily readable like you said haha.

…ecord batch (IBM#3120) Replace the `tmp > 2*math.MaxUint16` arbitrary number safety blanket with `tmp > MaxResponseSize` as we already have that constant (that a user can change via sarama.MaxResponseSize = ...) which is what we use for MaxBytes in a FetchRequest. Also added a test for large record counts. Fixes: IBM#3119
