WIP - Resolve "As a user, I want to run the Easy Install FROM ANDROID in order to install my device"

hi, this is further to the /e/asy installer being developed for Windows: https://gitlab.e.foundation/e/tools/easy-installer/-/merge_requests/64 I remember that the old Cyanogenmod "easy installer" was an app for Android, that you could download on your mobile, and that then would take care of the entire install process for you. I think that was great, and really easy. Hereby a request to make this also possible for the /e/asy installer, to be able to revert to /e/ without any PC, directly from the mobile phone.
