Suggestion: multi-thread collapsePathways

[Horokhovskyi]

Hello, I am an active user of the package. Sometimes running the collapsePathways function takes very long even with default number of permutations. Have you considered implementing a multi-thread version, for example via MulticoreParam ?

Can you attach (or send me by e-mail) the example when it takes too long? I believe that adding the multicore support is not that trivial to be effective for this function. So I need an example to understand trade-offs better.
