v1.4.0

Add support for dataclass components:

from dataclasses import dataclass
from markupy import Component, View, tag

@dataclass
class Title(Component):
    id: str

    def render(self) -> View:
        return tag.H1(".title.header", id=self.id)[self.render_content()]

And then:

>>> print(Title(id="headline")["hello "])

This will render as:

<h1 class="title header" id="headline">
    hello
</h1>
