feat(security): add injection prevention

Changes

I have added a new prepared tagged template literal, which helps protect against injection. I'll need confirmation on whether or not this is enough. See #137.

Test

An example of how to use it:

var session = new Session();
const someDynamicFirstNameWithInjectionAttack = "Mathias' or 1 = 1"

session.query(prepared`select foo from Bar where blah='${someDynamicFirstNameWithInjectionAttack}'

//the resulting query is:
//select foo from Bar where blah='Mathias\' or 1 = 1'

Good idea! Works well to stop the kind of injections you mention in #137 and I tried my best at breaking it and it seems robust. I added a test suite to it.

Since the code is rather short, some of my comments are borderline bikeshedding.

Once again great feedback! I applied some changes.

I changed some more stuff based on review. Should be ready now? 🤞

Fix the merge conflicts and it's ready to go

Alright, should be good to go now!
