patch: optimized adding any

[Andersama]

Instead of inserting, modify the point set to its now equivalent form.

Lowers compilation time, especially on more complex regexs.

[hanickadot]

please update it to latest main run make single-header

[Andersama]

I updated it to the latest, but I don't have make on my system.

[Andersama]

@hanickadot worked out how to get make going, think this is what you wanted? Any other pr's you're interested in that I should go back and update?

[hanickadot]

I just prefer to not forget about single-header versions, sometimes they divert, and I'm surprised. That's all :)

[Andersama]

@hanickadot you may want to add #183, although looking at it, I think I forgot to merge if the point was the last in the list. I can't remember if it was this or the other pr which made a bigger difference to compile times.
