feat: simplifies the whole gradle plugin

- the `compileFregeTask` has a new optional input called `mainModuleName`. If
it is set, it and only its dependencies will be compiled, otherwise all
`.fr`files in the `mainSourceDir`will be compiled.

- the internal `DependencyFregeTask` is deleted because it was only
used by the vscode plugin and I decided to remove this gradle plugin
as a dependency.

- an example project folder was added to test the plugin manually.
