Hello @mendsley,

I do not think you might be interested on the following changes, but if you are just drop me a line and I will create one or two pretty pull requests for these : )

a) breaking change
I have replaced the fixed bucket size of [8*3] bytes for patches as seen in offtin and offtout functions to a variable length encoding that can take from 1 to 10 bytes for each 64-bit signed integer encoded. That makes a range from 3 bytes (best case) to 30 bytes (worst case) instead of a 24-bytes fixed case.

Pros:

• smaller patches to the wire, which is more important to me.

Cons:

• patches are not backwards compatible anymore (neither with bsdiff tool).
• someway slower (overhead from 3 to 30 callback calls instead of a single call of 24 bytes)

b) fix for #1
I have applied the solution as seen on this thread

Pros:

• It seems to work.

Cons:

• it would need some more (real) extensive testing and/or proper unit testing to see I did not break it.
• the license for SAIS is MIT instead of BSD-2 :/

Happy new year btw,

• r-lyeh
