[IO-515] Add constructors that allow the initial size of the in memory
buffer
Add constructors that allow the initial size of the in memory buffer to be
set to a value other than the default value in ByteArrayOutputStream. The
current default is 32B which can have large performance impact if the threshold
is large enough due to multiple array doubling iterations. As an example, to
buffer 1MB the array would double 15 times and would create approximately 1MB
of garbage arrays in addition to the 1MB of buffer at the end.
