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.
