camino 1.0.7

Added

• Utf8Path::is_symlink checks whether a path is a symlink. Note that while std::path::Path only
  provides this method for version 1.58 and above, camino polyfills the method for all Rust versions
  it supports.

Changed

• Update repository links to new location camino-rs/camino.
• Update structopt example to clap 3's builtin derive feature.
  (camino continues to work with structopt as before.)
