WIP: Enhance inject route utilities

[Dafnik]

Adds the following options to all utilities and therefore aligns them.

• injectParams
  • transform
  • defaultValue
  • injector
• injectQueryParams
  • defaultValue
  • injector
• injectQueryParams.array
  • defaultValue
  • injector
• injectRouteData
  • defaultValue
  • injector
• injectRouteFragment
  • defaultValue

I also took the chance to rename initialValue to defaultValue (as I think it's a more fitting name).
injectQueryParams supports both values, as to not introduce a breaking change.

Tests are still missing.

is this still WIP?

[Dafnik]

Yes, docs and tests are missing.

Hello @Dafnik
Thanks for this great PR.

Regarding

I think initialValue is a better fit there because after the initialValue, the params can change however the router needs, and we shouldn't call it default value (as that would mean that we will reapply it again based on some condition, which we don't because we only need it the first time).

Hi, thank you very much :)

But it is actually a default value. 😅

Lets say we have the route test and use the URL /test?a=1234.
If we use injectQueryParams('a', {defaultValue: '1111'}) we will get the result 1234.
But now the route changes to /test. The query param is null and the default value 1111 will be emitted.

Or did I get this wrong?
