Move project to Forge namespace, and rename to SecureModules

Rewrite the ClassLoader to properly find resources from parent layers, support supplying a parent class loader and be easier to understand.
Compatibility with cpw land SecureJarHandler is kept until next major breaking window. Targeting MC 1.21 if I don't forget.
This project will need to be re-evaluated on if it even is necessary in the MC runtime at all.
Yes, Jar signatures/code signers are great. However we exist in a world of coremods and runtime bytecode manipulation. There is no possible runtime security need for this.
Things should be addressed in the MC universe using static analysis of the jar files themselves not runtime. Which can be done in a FAR simpler manor.
