New Gen Operators for MC

Two new Gen operators work in the context of mc.gen~ and mc.gen: mc_channel and mc_channelcount. These two operators provide the current channel (starting at 1) as well as the total number of channels in the mc.gen~ or mc.gen in which the Gen patch is embedded.

These Gen operators make it possible to do voice-specific calculations. You can also connect them to the Gen out operator to provide voice-specific identification signals or events outside the Gen context.

When used in a patcher inside gen~, mcs.gen~, or gen (in other words, outside the context of the MC Wrapper), both operators output 1.
