Improve Code.toBytes() performance

[OlegMazurov]

Problem

Code.toBytes() creates an instance of ByteArrayOutputStream() which in turn creates default byte[32] in its constructor.
Every time the current capacity is exhausted the underlying array is doubled in size and copied over, which has visible performance impact. That could be avoided by properly sizing the instance at creation.

Solution

Either a better default size could be used universally (256? 512?) or the actual size of item could be computed and passed to ByteArrayOutputStream(int). Performance effect of either solution should be evaluated.

Alternatives

I wonder if doing a measureRecord() is worth performance cost wise🧐 it then we would know exact size to allocate byte[] then?
