Cargo.toml, Cargo.lock: change dependencies used for logging

- replace log crate with tracing,
- replace simple-log crate with tracing-subscriber and tracing-appender
- add nu-ansi-term crate as a dependency which is itself tracing-subscriber's dependency,
  inorder to write colored outputs to the terminal since we override formatting provided
  by tracing-subscriber
