```
    Sorts the given list of MediaType objects by specificity.
    Given two media types:
    1. if either media type has a wildcard type, then the media type without the wildcard is ordered before the other.
    2. if the two media types have different types, then they are considered equal and remain their current order.
    3. if either media type has a wildcard subtype, then the media type without the wildcard is sorted before the other.
    4. if the two media types have different subtypes, then they are considered equal and remain their current order.
    5. if the two media types have different quality value, then the media type with the highest quality value is ordered before the other.
    6. if the two media types have a different amount of parameters, then the media type with the most parameters is ordered before the other.
    For example:
    audio/basic < audio/* < */*
    
    audio/* < audio/*;q=0.7; audio/*;q=0.3
    
    audio/basic;level=1 < audio/basic
