Review Comment:

only add deltaOne if bottom is not full of 0xff
It seems only work for `int` and `long`:
```java
float maxFloat = Float.MAX_VALUE;
float minFloat = Float.MIN_VALUE;
byte[] maxFloatByte = new byte[Float.BYTES];
byte[] minFloatByte = new byte[Float.BYTES];
FloatPoint.encodeDimension(maxFloat, maxFloatByte, 0);
FloatPoint.encodeDimension(minFloat, minFloatByte, 0);
```
result was maxFloatByte: [-1, 127, -1, -1] and minFloat: [-128, 0, 0, 1]
