Support for Text Prompt

[a333klm]

I want that the model segments based on an input string, e.g. "red cars".
It seems that this is not yet supported in this implementation.

If I find time, I could try to add this. But I need a starting point.
Can you give some advice?

Thanks for sharing this repo. It really helps.

I can add this API. But is Text Prompt input only supported by FastSAM?

It seems that might be true.
I think I saw it in one of the SAM models and incorrectly assumed it is available for all of them.
