Description
anstream currently has two modes: Printing all ANSI sequences, and stripping all ANSI sequences (StripStream). Would it be possible to add a third mode SanitizeStream, that allows color and similar text formatting streams, but strips potentially dangerous actions such as setting the terminal title?
This request is due to https://github.com/tokio-rs/tracing/issues/3378, where tracing now allows either escaping ANSI (not stripping, leading to bad output with strange characters), or turning off this validation completely. Does this fit in the scope of anstyle?

Research direction
Start by reading the existing StripStream behavior and the requested SanitizeStream mode described here. Establish which formatting sequences remain allowed and which dangerous actions, such as terminal-title changes, must be removed; done means preserving color and similar text formatting while stripping those actions.
