rich_format

rich_format replicates python string formatting for rich Text instances adding the possibility to substitute also with Text.
>>> from rich.console import Console
>>> from rich.text import Text
>>> import rich_format
>>> console = Console()
>>> text = Text("Hello {name}",style="red on white")
>>> formatted_text = t.format(name=Text("pom11"))
>>> console.print(text)
Hello {name}
>>> console.print(formatted_text)
Hello pom11
