In this commit, we create a new chainfee package, that houses all fee related functionality used within the codebase. The creation of this new package furthers our long-term goal of extracting functionality from the bloated `lnwallet` package into new distinct packages. Additionally, this new packages resolves a class of import cycle that could arise if a new package that was imported by something in `lnwallet` wanted to use the existing fee related functions in the prior `lnwallet` package.
