[Feature]: Add "bulk reject"

[mdeweerd]

Requirements

• I have updated Mushroom to the latest available version
• I did a search to see if there is a similar issue or if a pull request is open.

Is your feature request related to a problem?

One of the collection types is "bulk reject" (or "Encombrants" in French).
I think that this could be a specific waste type rather than "other".

Describe the solution you'd like

Add another waste type that would have the short name "bulk".

Describe alternatives you've considered

The alternative is to have it covered by "other", but other could refer to other cases for instance for "dangerous waste".
