* 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.

Wiggle is a code generator for the host side of a witx interface. It is
invoked as a Rust procedural macro.
Wiggle is not specialized to any particular WebAssembly runtime. It is usable in at least Wasmtime and Lucet.

Read the docs on docs.rs.
There are child crates for integrating with Wasmtime and Lucet.
The wasi-common crate is implemented using Wiggle and the wasmtime-wasi crate integrates wasi-common with the Wasmtime engine.
Andrew Brown wrote a great blog post on using Wiggle with Wasmtime.
