Increase the memory size for the Aqualung i770R

Browse Source 
The Aqualung i770R appears to have 6M instead of 4M (high) memory.
Confirmed by trying to read past the 6M limit, which fails with a NAK
response. This amount also matches with the capacity stated in the
manual (6553 hours of profile data at a 60 second sample rate).
