Update spas dependencies

[guilhermebene]

During the development of spas, I had to fork the repositories ALP4lib because some features had minor issues that would not work properly with spas.
You can see in

spas/setup.py

Line 15 in b486bcb

'ALP4lib @ git+https://github.com/guilhermebene/ALP4lib.git@7e35abf3a5c2e31652f7cfb2e4243b279b6a3a47',

that spas actually looks for those forks in my personal github account.
It would be nice to revisit these points and maybe update update the setup.py so that it gets specific versions of ALP4lib from their Pypi or github officiail pages instead of for the fork I had done.
