Description: 
BigDecimals that represent integer numbers can take up a lot of space, when 
scale is specified:
{code:java}
 BigDecimal dc = new BigDecimal("").setScale(1024, 
RoundingMode.HALF_UP);
System.out.println("Difference:");
System.out.println(MarshallerUtil.sizeInBytes(dc) - 
dc.stripTrailingZeros().setScale(0, 
RoundingMode.HALF_UP).unscaledValue().toByteArray().length);
{code}
The code prints:
{code}
Difference:
427
{code}
Let's update BinaryTuple format to store such numbers in more compact form that 
does not store trailing zeros.
