José de Paula Rodrigues Neto Assis 97e0651555 Be more lenient on accepting SAGA versions
Even though SAGA explicitly does't follow semver conventions, there are
advances, and not all changes on their part break the API. Since the
user is already warned in big letters that versions different from 2.3
are unsupported, in beta status, we've changed the requirement for SAGA
"beta" from 7.3 to everything in version 7.
