Cargo.toml,README.md: Bump version to 0.2.0

It's been a long time since v0.1.0, and even though we have a bunch of
things to address and implement, it's probably going to take some more
time before anything concrete happens.

Let's release v0.2.0, to at least fix audit reports for projects
depending on rbpf (see commit 196e5375896c ("deps: update time crate
version.") -- we were not affected but would trigger CVE scanners).
