Component methods 🔥
Minimal ex:

```nim
component MyComp:
  `template`:
    ...
  ...
  
  [methods]:
    # Here allows only procedures, methods, iterators and converters
    # The `self` argument is automatically generated here
    proc helloWorld*(arg: type) =
      ...
    method otherMethod*() {.base.} =
      ...
    method sum(a, b: int): int =
      ...
```
