Update deps

Update deps.

[prestwich]

wrt optional deps, our semver policy treats their breaking changes as semver major for us. We typically update by adding support for specific versions (see #403 and the discussion in #404). If you have a need for support for these crates at specific versions we can add those versions to the support directory, but modifying (removing) the existing support is a no go from our side

Can you help me with that? I wanted to update deps to reduce the number of outdated deps in my project.

If I want to update primitive-types, rlp and ethereum_ssz, I have to add new features for those updated deps?

I think that #403 is a pretty good roadmap for achieving that. The basic steps are

• add the new dependency with version number in name (renaming the old one to include a version number too)
• add the new file to support/
• edit the existing support to use the renamed version of the old package
• do NOT edit the feature name

in the meantime, i'm closing this as wontfix as this PR would violate our semver policies. would love to see followup PRs tho :)
