Optimizations plus bug fix (#541)

Browse source 
* Optimize `Download::and_extract`: Avoid dup monomorphization
* Increase buffer size for binstall_crates_v1 to `4096 * 5`
* Optimize `opts::resolve`: Avoid unnecessary `clone`s
* Fix reserve in `opts::resolve`: Do not over-reserve
* Rename field `opts::Options::resolver` => `resolvers`
* Refactor: Extract new type `resolve::PackageInfo`
    - which makes `opts::resolve_inner` easier to understand
    - reduce number of parameters required for `download_extract_and_verify` and
      `collect_bin_files`
    - reducing size of future returned by `opts::resolve_inner` by dropping
      `cargo_toml::{Manifest, Package}` as early as possible since
      `Manifest` is 3000 Bytes large while `Package` is 600 Bytes large.
* Optimize `fetchers::Data`: Use `CompactString` for field name & version
   since they are usually small enough to fit in inlined version of
   `CompactString`.
* Optimize `gh_crate_meta`: Avoid unnecessary allocation
   in `RepositoryHost::get_default_pkg_url_template`.
* Refacator: Use `Itertools::cartesian_product` in `apply_filenames_to_paths`
* Optimize `ops::resolve`: Avoid unnecessary `clone` & reduce future size
   by calling `fetcher.target_meta()` to obtain final metadata after
   downloaded and extracted the binaries.
* Optimize `ops::resolve`: Avoid unnecessary allocation
   in `download_extract_and_verify`: Replace `Itertools::join` with
   `Itertools::format` to avoid allocating the string.
* Fix disabling cargo-install fallback
* Simplify `BinFile::from_product`: Takes `&str` instead of `&Product`
   since we only need `product.name`
* Rename `BinFile::from_product` => `BinFile::new`
* Refactor: Create newtype `ops::resolve::Bin`
   so that we don't need to `unwrap()` on `Product::name`
   and reduce memory usage.
