chore(deps): relax dependency requirements

[ozgb]

Summary

This removes the requirements for exact dependencies - this allows apps
that depend on this project to accept bug fixes from it's dependencies,
and improve interop with other packages.

Context:
We have some integration test in the Midnight node
that use Whisky, but we're having to use a fork of the project to resolve
dependency incompatibilities with wasm-bindgen.
