Add new cargo release for unicorn2

[lockbox]

Since the ffi is exposed on dev branch now, and the set_cpu_model enums have been added (among others), can the maintainers push a new cargo 2.0.x release? thanks

I'm planning a 2.1.0 release. We usually make a monolithic release for everything so please wait a bit.

At the same time, you could always use something like:

xxx = { git = "xxxx", branch = "xxxx"}

Yeah that's what I'm doing atm
