Write-only access to an atom

Returns a setter function for an atom without subscribing to changes. The component won't be checked for changes when the atom updates.

## Usage

```ts
import { Component } from "@angular/core"
import { atom } from "valdres"
import { injectSetAtom } from "valdres-angular"

const countAtom = atom(0)

@Component({
    selector: "app-increment",
    template: `<button (click)="increment()">+</button>`,
})
export class IncrementComponent {
    private setCount = injectSetAtom(countAtom)
    increment = () => this.setCount(c => c + 1)
}
```
