v2.0.0

• #22: Fixed design flaw that based on the usage of ThreadStatic properties. This unfortunately lead to slightly more effort in setting up the mock and prevented its usage outside a queue context.
• #25: Add .PreventAllOtherInvocationsOf method to ensure no other methods were called
• #20: Support .net9
• #19: Introduced CallQueue.Empty
• #23: Enabled support for .Callback calls. This was not possible before as calling .Callback would overwrite the internal call-detection
