Unable to build with `openssl 0.10.39`: cannot find function, tuple struct or tuple variant in crate `ffi`

[pan93412]

Seems like there are some breaking changes introduced in the openssl-sys v0.9.73 version.

[sfackler]

Oops, I forgot to update openssl's version requirement on openssl-sys. A cargo update should get it compiling.

[bgilbert]

Would you consider releasing a new version with this fix, so everyone doesn't need to manually fix up their Dependabot PRs?

[sfackler]

Yep, done
