In theory could invent an OTEL_TRACES_SAMPLER and OTEL_TRACES_SAMPLER_ARG if that makes more sense, but this seemed fine for now.

Should this default to 1 instead of 0? I'd been using 0 with some testing to prevent flooding as I was more interested in Traceheaders, but the default OTEL sampler is "parentbased_always_on".

A value of zero seems like the expected default, so that no sampling is done.

Lgtm.
Rebased on top of #150 to use release version of boxo and libp2p/go-libp2p-routing-helpers#84 + added changelog / some docs. Merging – I will continue and release tomorrow.
