Replace manual traversal with ipfs.resolve

[lidel]

AFAIK at the time this project was created ipfs.resolve was not present in js-ipfs, and we had to do the traversal manually.

Since then ipfs.resolve landed in js-ipfs so this may be worth checking.

js-ipfs-http-response/src/resolver.js

Lines 56 to 57 in 076fde3

	// TODO: replace below with ipfs.resolve(path, {recursive: true})
	// (requires changes to js-ipfs/js-ipfs-api)

Things to check:

• does resolve work the same in go-ipfs and js-ipfs (eg. how HAMT directories are handled)
• it should transparently take care of sharded directories
