Remove Node/Remove Line Actions

[gerrymanoim]

Recently in a refactor I ended up creating actions to remove a matching node and the entire line it was on, which I think might be useful to others.

Would you accept these in a PR?

from refactor import Action

class RemoveNodeAction(Action):
    """A action that removes matched segments"""
    def apply(self, context: Context, source: str) -> str:
        """Refactor a source segment in the given string."""
        lines = split_lines(source)
        view = slice(self.node.lineno - 1, self.node.end_lineno)

        target_lines = lines[view]
        lines[view] = [
            target_lines[0][: self.node.col_offset] + target_lines[-1][self.node.end_col_offset :]
        ]

        return lines.join()

class RemoveLineAction(Action):
    """A action that removes matched segments"""
    def apply(self, context: Context, source: str) -> str:
        """Refactor a source segment in the given string."""
        lines = split_lines(source)
        view = slice(self.node.lineno - 1, self.node.end_lineno)

        del lines[view]

        return lines.join()

I was actually thinking about this a while, but never needed it. It definitely fits as a use case, and would love to see it on the core! Shoot the PR 🚀
