Fixes #107 This is a big change that does the following: - replaces the bespoke exec implementation with an impl inspired from the nomad cli, using the client directly - add a wander exec command - therefore tls is supported - improves general exec experience (can move cursor, does not strip ansi escape sequences, etc) - BREAKAGE: exec with wander serve breaks. Unfortunately with this impl, tea.ExecProcess is used, which is currently charmbracelet/wish#196
