[REVERT] support for (non- &) enumerable props & symbols 💥

I reverted latest version to version 1.2.4!! (now pushed as 1.4.0)

Reverted the: Support for (non- &) enumerable props & symbols 🦄

The latest pushed branch is now:
https://github.com/mesqueeb/copy-anything/tree/revert-to-1.2.4

Reason:

Copy'ing non-enumerable props by default caused A LOT of applications of mine to crash because my copies were receiving those hidden props that were previously not there, which caused to break reactivity in many cases.

If you still need to copy (non- &) enumerable props & symbols then please set version to 1.3.0.
I need to think of the best way to make this optional instead.
