Please set types property in package.json

[FrozenKiwi]

This issues has popped up intermittently in my codebase over the past few months, so it is influenced by build options and should be able to be workaround somehow, but it's also pretty unnecessary and very easy to fix.

** Problem **
Without a types property, the compile fails eventually when tendermint is trying to import create-hash with

Could not find a declaration file for module 'create-hash'. 

because tsc ends up compiling the wrong src version. You can see it in the module resolution: note the 2nd resolution where the resolve looks for types

** Workarounds **
Note: --skipLibCheck does not fix this for me.

in .d.ts file:

declare module 'create-hash';

** Fix **
Adding types folder to package.json removes the error, and gives the following resolution stack (note that the resolution finds stops after it finds the .d.ts file
