@xcarpentier Thanks for the PR!

Is there any harm in including all forms of auth? As in can we keep old headers around as a fallback?

FYI: A lot of this lib's functionality was deprecated because expo's command line tool (exp) has a lot of these automation utilities implemented now. See github.com/mglagola/exptool/wiki/Deprecations

Hi @mglagola,

I wasn't sure but I guess sessionSecret was there before last exp version, no? (I will figured out)

If not I will change the PR to integrate Authorization & Exp-Access-Token if into $home/.expo/state.json.

expo's command line tool: yes I know, my use case is that I need to keep build chain as it is but just upgrade without changing code for now.
