JNet development state

This release comes with some ready made classes:

• JNet:
  • Reflected almost all classes of a Temurin JDK 11 with the limits imposed from JNetReflector
  • Manually made some classes, or extended some of reflected one, due to limitations of JNetReflector
  • If something is not available use API extensibility to cover missing classes.
• JNetCLI: added REPL shell, run Main-Class and execute C# scripts
• JNetReflector: builds listeners and reflects Java classes with constructor, methods, fields, conversion operators and documentation
• JNetPSCore: base implementation for JNetPS
• JNetPS: some PowerShell cmdlets
