[FEATURE]: Upload binary package from the UI

[coiseiw]

Description

When using an offline platform for Hashtopolis, using an online URL is not working for adding a new version of the cracker. The typical solution that I know is to place the binary inside one reachable folder from the main server and use this as the URL. Yet this requires some manual intervention, requires to use a mounted folder for the docker, and is prone to error.

I believe that offering an option to upload the package from the local machine - as done for files for examples - would simplify the process and avoid errors.
