Support git lfs

[garyo]

It seems githack.com does not work with git lfs. Here's a test repo (not mine) with an LFS file: https://github.com/Schoonology/git-lfs-test - the file binary.jpg is stored with LFS. If I understand how githack is supposed to work, I should be able to wget that file straight from githack.com:

wget https://raw.githack.com/Schoonology/git-lfs-test/master/binary.jpg

But that just returns the pointer file:

% head binary.jpg
version https://git-lfs.github.com/spec/v1
oid sha256:6fe2e48ef494b7855e6d8f93c59cf38d38350274e304a9ac35102d5c365ee002
size 620773

which is not good.

Downloading straight from github raw works fine:

% wget https://github.com/Schoonology/git-lfs-test/raw/master/binary.jpg
% file binary.jpg.2
binary.jpg.2: JPEG image data, JFIF standard 1.01

but downloading using raw.githubusercontent.com (which may be where githack.com is proxying from?) does not:

% wget https://raw.githubusercontent.com/Schoonology/git-lfs-test/master/binary.jpg 
% file binary.jpg.3
binary.jpg.3: ASCII text

So it would appear that at this point, githack doesn't support LFS. It would be great if it could!

It is related to #16 and I am currently working on that. Thank you.
