fix: resolved an issue where types were not being properly picked up in some ESM TS projects (resolves #62)

[ClockRide]

Resolves #62.

I found that this package was causing type errors in my application. The proposed solution is the least intrusive I have found. I considered overhauling the bundling pipeline altogether using something like Rollup. While it seems to be a better way of achieving ESM+CJS compatibility, it could present breaking changes and have all kinds of side effects, so I opted for patching package.json instead.

Yep, unfortunately this is more less the only way, although I've had issues with referencing the same file before. If this works, LGTM, otherwise we may need to overhaul the build script 🫠
