The semantics of int-to-pointer casts under strict provenance has changed. Ideally, we would update our From<usize> for Register implementation to use the sptr crate, but sptr does not currently have a suitable license. There is a PR to change that, but it hasn't gotten a response in 7 months, so I don't think we can use it. Instead, this copies the implementation of core::ptr::invalid.
This also bumps our thiserror dependency, which forces Cargo to pick a newer version of proc-macro2 that is compatible with recently nightly toolchains.
