We now support negative values. This will allow us to
store time/value sequences that are not monotonically
increasing, so that we do not have to create multiple
files just because some values were send out of order.
This is done by first transforming the values into
positive values by using interleaved encoding (there
is a name for it, but I don't remember it). We are
mapping values like this:
0 -> 1
1 -> 2
-1 -> 3
2 -> 4
-2 -> 5
...
Renamed LongSequenceEncoderDecoder to VariableByteEncoder.
Made methods static.
