[PFM][API Request] Remove producer rule

[tlitookilakin]

Hi. I've written a mod that overhauls the production logic for bee houses. Unfortunately, PFM's default config includes an entry for the beehouse, which renders the mod mostly nonfunctional. If the PFM API included a function that allowed c# mods to remove specific producer rules, then I could use that to disable the bee house producer when my mod is installed, to prevent things breaking.

Alternatively, I could open a PR for PFM that disables the bee house producer if it detects my mod, but that seems like the less good option of the two.

(It's actually the CustomProducerMod PFM pack that includes the bee house, not PFM itself. this would still be a useful feature, but it's not necessary here.)
