Remove unneeded dependencies

[Koeng101]

This PR removes dependencies that are not strictly needed.

The following were/are going to be added directly to source tree: They're pretty much complete (no updates in years), so it is easier to just manage them internally:

• svb
• intel-cpuid (used by svb only)
• murmur3
• wordwrap

On the top level go.mod should be replaced with a go.work file, with the submodule of the lib of DNA design being separate from the services. lib right now will only have Go project dependencies, but this may change if there is a sufficiently useful package that cannot be integrated into the source tree directly. In addition to lib, we will also have a wasm_lib directory with wasm dependencies, like minimap2, diamond, and sqlite (plus the required wazero). This repo will have minimal dependencies as well.

Once we get into services, it's a little bit more of the wild west. We will at least require:

• github.com/sashabaranov/go-openai (for communicating with LLMs, actively developed)
• github.com/yuin/gopher-lua (for running lua, actively developed)
• github.com/oapi-codegen/runtime (for generating OpenAPIs)
• github.com/getkin/kin-openapi (for handling OpenAPI specs)
• github.com/caddyserver/caddy (for scraping websites like iGEM or Addgene)

Plus associated javascript like scalar

Forgot to add: in Go 1.22 they're going to add better routing to the std, removing the need for chi. So that's nice.

Keeping github.com/google/go-cmp for checking equivalence of lists and golang.org/x/sync for errgroup.

Big todos:

• [x] Update seqhash to be more explicit about version 1 depreciation
• [x] Write about the 4 internal packages (svb, cpuid, wordwrap, and murmur)
• [X] Refactor codon completely. I am removing a lot of cruft, and really slimming down the implementation. Do this in a separate PR.
