Initial redirects implementation (#148)

Adds basic support for `_redirects` files. It supports a subset of what IPFS supports: https://docs.ipfs.tech/how-to/websites-on-ipfs/redirects-and-custom-404s/

Example:
```
/redirect https://example.com/ 301
/another-redirect /page 301
/302  https://example.com/  302
/app/* /index.html 200
/articles/* /posts/:splat 301
```
301 redirect: https://video-prize-ranch.localhost.mock.directory:4430/redirect
SPA rewrite: https://video-prize-ranch.localhost.mock.directory:4430/app/path/path
Catch-all with splat: https://video-prize-ranch.localhost.mock.directory:4430/articles/path/path

Closes #46
