(This is similar to 908fb8 but for memory regions) Removes the weird offset encoding in favour of a metadata structure, similar to what there was before. However this structure overlaps with the cache ram itself and grows like a stack. This is to avoid wating memory since most games only use a few blocks. Simplify the "dual" block lookup routines too, since they are only an extrypoint to the other two real modes.
