Compile on rust 1.61, resolve warnings, fix some lints (#12)
* Fix getopts version The pinned version does not compile anymore because of mutable aliasing: * https://github.com/rust-lang/getopts/pull/61 * https://github.com/rust-lang/getopts/issues/110 This was achieved by temporarily setting the getopts version to "0.2.21" in Cargo.toml, and running `cargo check`. Note that this also converts the Cargo.lock to a new format. * Fix warning: Instead of deprecated macro try!, use question mark operator * Fix warning: Avoid anonymous parameters * Fix warning: Use dyn on trait objects * Fix warning: Avoid unneeded mutability * Fix warning: Avoid redundant format in panic or assert * Fix lint: Avoid redundant field names in initializers * Fix lint: Avoid redundant clone * Fix lint: Avoid literal cast * Fix lint: Collapse if/else where applicable I left some if/else branches in place, if there was a certain symmetry between the branches. * Fix lint: Avoid needless borrow I left some if/else branches in place, if there was a certain symmetry between the branches. * Fix lint: Use cloned instead of custom closure * Fix lint: Avoid unneeded trait bound * Fix lint: Avoid unneeded trait bound (2) avoid redundant clone * Fix lint: Use &[T] instead of &Vec<T> * Fix lint: Avoid & on each pattern * Fix lint: Avoid manual assign * Fix lint: Use implicit return * Fix lint: Merge if/else branches with same value I left one complicated branch in place. * Fix lint: Use is_empty instead of comparing len against 0 * Fix lint: Use sum instead of fold * Fix lint: Avoid clone on Copy types
