Move CSharpCodeMatcher to a new project (#548)
* matcher
* wip
* fix
* <VersionPrefix>1.4.0</VersionPrefix>
* .
* x
* ?
* netstandard2.1
* {}
* test
* Fix: Assembly with same name is already loaded
* _format file
* AssemblyFile = $"WireMock.CodeHelper.Class{Guid.NewGuid()}"
* AssemblyFile = $"WireMock.CodeHelper.Class{Guid.NewGuid().ToString().Replace("-", "")}"
* GC
* x
* remove load ex
