It's on my list to revise and include a slop~ based compressor/expander/limiter based on slop~ in my tutorial.

I do have a compressor~ object but it uses some other approach.

The main difference between a limiter and a compressor is the ratio, so you can use any comprssor as a limiter.

The soundhack library has a compiled object for compression and expasnion. I could offer a modification of that one and that was on my list as well.
