Newer MM2 version doesn't fit into an ATTINY85 anymore

[ManoDaSilva]

Hi!

Congrats on getting this library so far! I'm currently working on an extremely compact decoder for electric turnouts... The lib work beautifully on an ATMEGA328, but once I try to port it to an ATTINY85, I run out of space (global variables at 217% with the unmodified GetBits example).

I tried reducting the MM_QUEUE_LENGTH to 4 (as older versions of your lib did), but no success... Is the extra mem needed for MM2 decoding, or is there something I could do to reduce memory usage?

Thanks for your help!
