 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.
