feat: add types (#106)

* feat: add types

Adds ts types, fixes all tsc errors.

Removes ipfs/ipfsd-ctl/ipfs-http-client dev deps as we only spin up
a node to get an IPFS id which we can just hard code for testing purposes.

Replaces protons with protobufjs as elsewhere in the stack.

* chore: do not double-build

* chore: add types directive to package.json

* chore: update ubuntu version

* chore: remove redundant pre publish step
