[v2.0.0] Could not find a declaration file for module 'geostats'.

[JeomJeom]

Describe the bug

I intend to use geostats in typescript file, but i got this error message: Could not find a declaration file for module 'geostats'... when importing it.

This is the full message showing on my Webstorm:

TS7016: Could not find a declaration file for module 'geostats'. '.../node_modules/geostats/lib/geostats.min.js' implicitly has an 'any' type.   Try npm i --save-dev @types/geostats if it exists or add a new declaration (.d.ts) file containing declare module 'geostats';

I've tried to run npm i --save-dev @types/geostats, but @types/geostats doesn't exist. Could anyone help me on this issue?
