Specify sequence using context from the previous function (e.g Annotations)

Related issue: https://github.com/crossplane-contrib/function-go-templating/issues/154
### What problem are you facing?
We currently maintain a couple of medium-sized compositions using function-go-templating. We observe, that dependencies between the composite resources are unavoidable and therefore we are seeing ourselves a lot inside conditional blocks, which get fairly complex to oversee on a larger scale.
While this function addresses the problem, we lack a proper way of defining the sequences in a declarative way. Since we use the go-templating, resources names can be templated using user input and we cannot determine it well enough using regular expression matching.

### How could this Function help solve your problem?
We would somehow need a way of passing context from the previous function down to `function-sequencer` which bridges the gap between free templating and configuration.

One possible solution would be to extend this function to determine the sequence based on a special annotation similar to Argos [Sync waves](https://argo-cd.readthedocs.io/en/stable/user-guide/sync-waves/). The function will read the corresponding sequencing from the annotation.

It could look somehow like this:
```yaml
