feat: Angular 13 support (+rxjs 7)

[gloaec]

Hi,

First of all, i read some of your messages about the situation you are living right now, and I am really sorry that you have to go through any of this. I hope the situation gets better soon.

This is our modest contribution (with @MrP) to the project, i guess a couple of people are stuck migrating to Angular 13 rn :)

Anyway, let us know how we can help and get this merged.
In the meantime, take care and be safe :*

hey, thank you for the contribution! This is a breaking change because peer dependencies are changed to 13.0.0. Can be a patch release instead?

[gloaec]

Sure, or ppl will just change dependency to the new version I guess.

I don't know the release procedure though, should I do it or let you take things from here ?

Cheers

[gloaec]

Or maybe I missunderstood : you want to keep compatibility with Angular 12 ?

[stalniy]

ok let's merge it as it's. anyway, supporting multiple ng versions is a headache and starting from 13 there is no ViewEngine anymore what is good :)

[gloaec]

Alright :)

Thanks mate
