JavaScript heap out of memory when using findReferences() on many identifiers

Hi,
So i've tried transforming the entire lodash-es library using `ts-morph`

After around 50 modules (there are ~900 there) JavaScript runs out of memory, not to mention that it's very very slow on my speedy Mac, (what would happen on a slower machine on a some CI in docker - I can only imagine)

Do you have any plans on optimising it, or any tips on making it faster? I must find another solution to it, cuz it's not acceptable even for production builds where speed doesn't matter, but I didn't expect it to be THAT slow)

UPD.
the slowest operations, that makes it literally 50x slower is `findReferences`....
UPD:
Found the culprit: I was doing findReferences on every single Identifier instead of selected items. That just killed it. I still have big hopes for this library xD
