Bump version to 0.16.x, respect new tag names

With 0.16.x, we started to release the lychee CLI binary separately from
the lychee library. As a consequence, the crates get prefixed differently
on GitHub releases:

- CLI binary: `lychee-v0.16.0`
- Library: `lychee-lib-v0.16.0`

We need to account for that when downloading the binary, as shown in this commit.
