Ability to specify the order of any pack no matter who sends them

[Phoenix616]

Is your feature request related to a problem? Please describe.

When a server sends a pack which should be between two that the user already had applied before (e.g. from a proxy) then this isn't really supported right now.

Most likely this requires removing and resending any pack the client has which are not in the right order.

Describe the solution you'd like

A way to configure it, e.g. with a priorities list.

Describe alternatives you've considered

Maybe merging or trying to define a list per-server/world of which order all packs should have.

Additional context

Only applies to 1.20.3+
