Align core types with execution spec (#733) Since these types were written, we've gained an executable spec: https://github.com/ethereum/execution-specs This PR aligns some of the types we use with this spec to simplify comparisons and cross-referencing. Using a `distinct` type is a tradeoff between nim ergonomics, type safety and the ability to work around nim quirks and stdlib weaknesses. In particular, it allows us to overload common functions such as `hash` with correct and performant versions as well as maintain control over string conversions etc at the cost of a little bit of ceremony when instantiating them. Apart from distinct byte types, `Hash32`, is introduced in lieu of the existing `Hash256`, again aligning this commonly used type with the spec which picks bytes rather than bits in the name.

clean up eth_types (#531) `eth_types` is being imported from many projects and ends up causing long build times due to its extensive import lists - this PR starts cleaning some of that up by moving the chain DB and RLP to their own modules. this PR also moves `keccakHash` to its own module and uses it in many places.
