CC0022: Does not recognize the new C# 8 using statements

[MischaVreeburg]

CodeCracker is not currently considering the using pattern, as it ignores the using FileStream f = new FileStream(@"C:\users\jaredpar\using.md"); statement.

pattern-based using: https://docs.microsoft.com/en-us/dotnet/csharp/language-reference/proposals/csharp-8.0/using

CodeCracker will output a CC0022 even if the field is disposed:
`if (...)
{
using FileStream f = new FileStream(@"C:\users\jaredpar\using.md");
// statements
}

// Equivalent to
if (...)
{
using (FileStream f = new FileStream(@"C:\users\jaredpar\using.md"))
{
// statements
}
}`

Code cracker should not report a cc0022 for this new pattern

@MischaVreeburg We don't have C# 8 for now!
