* feat(ooapi): add toplevel client and simplify API This diff should simplify using ooapi from other packages by adding more abstraction that wraps the existing code. Part of https://github.com/ooni/probe/issues/1355. * fix(ooapi): use correct comment for cloners See https://github.com/ooni/probe-cli/pull/248#discussion_r590663843 * fix(ooapi): make sure the documentation is current See https://github.com/ooni/probe-cli/pull/248#discussion_r590665773 * fix(ooapi): automate copying APIs See https://github.com/ooni/probe-cli/pull/248#discussion_r590665837 * feat(ooapi): add unit tests for clientcall.go See https://github.com/ooni/probe-cli/pull/248#discussion_r590666297 * fix(ooapi): rewrite integration tests to use toplevel API See https://github.com/ooni/probe-cli/pull/248#discussion_r590665084
