I get build errors with a fresh checkout

I'm guessing that jsts has updated but you have an indeterministic version of it as a dependency? Anyway, I was trying to use your shapefile repo to see how well it parses shapefiles, and got a jsts error via this repo

Error: Cannot find module 'jsts'
Require stack:
- [my repo]/node_modules/ginkgoch-geom/dist/bundle.js
- [my repo]/node_modules/ginkgoch-shapefile/dist/bundle.js

so I pulled this repo down to investigate. When I clone this, run yarn then yarn build, I get these errors:

ERROR in .../ginkgoch-geom/src/types/Jsts.ts

(Looks like I can just comment out the three type defs in src/types/Jsts.ts to fix the build in this repo...)
