This encoding is adapted from the Binary packing described in ["Decoding
billions of integers per second through
vectorization"](http://arxiv.org/pdf/1209.2137v5.pdf) by D. Lemire and L.
Boytsov.
-In delta encoding we make use of variable length integers for storing various
numbers (not the deltas themselves). For unsigned values, we use ULEB128, which
is the unsigned version of LEB128
([https://en.wikipedia.org/wiki/LEB128#Unsigned_LEB128]). For signed values, we
use zigzag encoding
([https://developers.google.com/protocol-buffers/docs/encoding#signed-integers])
to map negative values to positive ones and apply ULEB128 on the result.

Delta encoding consists of a header followed by blocks of delta encoded values
binary packed. Each block is made of miniblocks, each of them binary packed
with its own bit width.
