Add maxTimeMS to FindOptions

[BrunoBernardino]

This is allowed, works, and is already being sent over, so it's really just a type thing.

[lucsoft]

can you add a test case please?

[BrunoBernardino]

Alright, will do!

[lucsoft]

one more thing the spec says that maxTimeMS should be a function like find().maxTimeMS() not an option parameter

but the tests look good! thanks so much!

Before 4.4, the documentation didn't explain much about errObj, and the codeName field might not be available before 4.2.

I think I've seen that for the mongo shell function but not for the node.js driver documentation. Can you link to where you saw that?

Took quite a while, but I finally nailed the problem. findOne doesn't seem to support maxTimeMS in mongo 4.0, only 4.2+, so it wasn't failing. I'm not certain if it's an implementation bug (unlikely since it works as expected for 4.2+), or simply something I didn't see in the documentation. You can see my journey in the commits, but hopefully the tests are good now.
