Single backplane

Another stream of discussion with my mentor focused on the backplane, and whether we should have 4 individual boards, or a single one. While the former option would allow customers to purchase a dual-channel version initially, then upgrade to a larger configuration over time, the latter option would significantly improve the quality of analog and digital signals.

Therefore, we decided to go for the single backplane option. Here is an updated design, which also take into account the adoption of the ADS7953 analog-to-digital converter, and adds 20 more pins to the submodule interconnect in order to carry individual ground levels across all 16 analog ports of a channel.
