Function generateMethodParamId

generateMethodParamId(method, contentDescriptor): string
Create a unique identifier for a parameter within a given method. This is typically used to create hashmap keys for method to parameter mappings.
Parameters
- method: MethodObject
  The OpenRPC Method which encloses the content descriptor
- contentDescriptor: ContentDescriptorObject
  The OpenRPC Content Descriptor that is a param in the method
Returns string
an ID for the param/method combo. It follows the format {method.name}/{indexWithinParams}|{contentDescriptor.name} where:
1. if the method's parameter structure is "by-name", the format returned uses the contentDescriptor.name
2. otherwise, the return value will use the params index in the list of params.
Throws
[[ContentDescriptorNotFoundInMethodError]]

Example
```
const { generateMethodParamId }
const methodObject = {
  name: "foo",
  params: [{
    name: "fooParam",
    schema: { type: "integer" }
  }],
  result: {}
};
const paramId = generateMethodParamId(methodObject, methodObject.params[0]);
console.log(paramId);
// outputs:
// "foo/0/fooParam"
```
