✨ Add meta data to trigger via components.

[T4rk1n]

Add a binding_meta keyword to Python Component to store extra information to be sent to the backend with the bindings trigger.

from dazzler.system import Page, BindingContext, Trigger
from dazzler.components import core

page = Page(
    __name__,
    core.Container([
       core.Button(
           f'click {i}',
           identity=f'btn{i}',
           binding_meta={'meta': 'info', 'index': i}
       ) for i in range(3)
    ])
)


@page.bind(
    Trigger(
        aspect='clicks',
        identity='btn',
        regex=True,
    )
)
async def on_clicks(ctx: BindingContext):
    print(ctx.trigger.meta['index'])
