Add ability to pull elements from robot based on specified properties

#### Description:

Raised up in https://github.com/orgs/BHoM/discussions/1439#discussioncomment-3924016

Could look into adding request to help filtering by a specific label, such as all bars with a specific section property assigned.

API seem to support creating selections based on a particular label type and name, that then could be used to filter out wanted objects:

`m_RobotApplication.Project.Structure.Selections.CreateByLabel`

Robot specific request making use of this feature could be useful.
