Exception filters are not supported in .NET Framework 4.7 and 4.8

[Miista]

Stack trace:

The requested operation is invalid for DynamicMethod.
   at System.Reflection.Emit.DynamicILGenerator.BeginExceptFilterBlock()
   at Pose.IL.MethodRewriter.EmitILForExceptionHandlers(ILGenerator ilGenerator, Instruction instruction, IReadOnlyCollection`1 handlers)

As per the documentation it should be possible to implement this using DynamicILInfo.
