Updating Dependencies (Objdiff-Core, typed_path added)

[EstreyaZR]

Objdiff-core isn't updated on cargo anymore. I added it back through a git dependency, and handled edge cases where due to breaking changes, objdiff-core expected typed_path::Utf8Path(Buf) for the configuration command.

Old Version: 2.5
New Version: 3.5.1

I didn't find a way not to have typed_path as a direct dependency, so I added it.

Thanks! To simplify things I added a to_utf8_unix_path_buf helper to shorten code elsewhere that need to convert std::path::PathBuf to typed_path::Utf8UnixPathBuf.

Also since objdiff doesn't require globset crate anymore to set the watch_patterns field, I've gone ahead and removed it as a dependency.
