feat: Allow static file config options

[cj]

Description

This allows you to set things like the cache_control for the static paths to improve lighthouse scores.

from litestar.datastructures import CacheControlHeader
from litestar_vite import ViteConfig, VitePlugin
from litestar_vite.plugin import StaticFilesConfig

VitePlugin(
        config=ViteConfig(
            hot_reload=env.debug,
            use_server_lifespan=env.debug,
            dev_mode=env.debug,
            port=env.vite_port,
        ),
        static_files_config=StaticFilesConfig(
            cache_control=CacheControlHeader(max_age=31536000, immutable=True, public=True),
        ),
    )
