Problems using boltwall in a typescript project

[bucko13]

This came up in one of the Pleb.fi projects. This seemed not to be a problem if using boltwall as a local dependency, so it seems maybe a problem in how the project is bundled and packaged from npm. Here are the errors reported:

node_modules/boltwall/dist/typings/index.d.ts:1:72 - error TS2307: Cannot find module './invoice' or its corresponding type declarations.
