Feature request:
In the <Multiselect> Vue component, it would be useful to be able to set a max number of selections per group. The groups aspect is already implemented so if this could be combined with a maximum per group, it opens it up to a lot of different possibilities.

My use case would be to be able to select 1 option from one group, and then have a second group with only 1 item, thus it means you can have a combination of any of the first, together with a toggle flag (the single option from the second group).

Examples:
Group1Option1 + [ empty ]
Group1Option1 + Group2Option1
Group1Option2 + Group2Option1
Group1Option3 + Group2Option1
Group1Option2 + [ empty ]

A similar request was implemented for the other libraries:

• In PrimeNg here: Feature Request: Selection limit for multiselect items primeng#4614
• And in PrimeReact here: [Multiselect] Feature request: Configure Maximum allowed number of items selectable in Multiselect primereact#1815

Would be great if this configurability can be added to PrimeVue as well.
