* Update to clap 3.0 This commit migrates all CLI commands internally used in this project from structopt/clap2 to clap 3. The intent here is to ensure that we're using maintained versions of the dependencies as structopt and clap 2 are less maintained nowadays. Most transitions were pretty straightforward and mostly dealing with structopt/clap3 differences. * Fix a number of `cargo deny` errors This commit fixes a few errors around duplicate dependencies which arose from the prior update to clap3. This also uses a new feature in `deny.toml`, `skip-tree`, which allows having a bit more targeted ignores for skips of duplicate version checks. This showed a few more locations in Wasmtime itself where we could update some dependencies.
