update deps + loosen some requirements (#12)

* update deps + loosen some requirements

rules:
- for crates that are below v1.0 -> specify the precise version
- If the code uses a feature that was added for example in X 0.3.17,
  then you should specify 0.3.17, which actually means "0.3.y where y >=
  17"
- for crates the are above or equal v1.0 -> specify only major version
  if the crate's API is minimal and won't change between minor versions
    OR specify major&minor versions otherwise

tested with https://github.com/taiki-e/cargo-minimal-versions

* fix warnings
