Macros to encode/decode URL

[etx121]

Describe the feature

With dbt-utils, we can use this to extract params for url:

{{ dbt_utils.get_url_parameter(field='page_url', url_parameter='utm_source') }}

However, sometimes, in the params, it is another URL which is encoded.
It would have been great to have macros directly included inside the package to encode/decode the URLs.

Describe alternatives you've considered

I am currently creating my own macros, it does the job (not 100% sure), but it would be better inside a maintained package, especially the one I am using to extract URL params. Here are the macros I am using:

{% macro url_decode(encoded_string) %}

Who will this benefit?

Example:
https://myurl.com?u=https%3A%2F%anotherurl.com%2Fsection%2F
=> extracted params from u: https%3A%2F%anotherurl.com%2Fsection%2F
=> decoded params: https://anotherurl.com/section/

See my macros above, but I am it can be better than that
