A rp2040-based ultrasound pulse-echo acquisition device

After a couple of iterations for single-element ultrasound pulse-echo devices, the pic0rick choses simplicity to reach a modular design, allowing for bipolar pulser, fast acquisition and relatively simple, barebone design. No FPGA, no BGA, plain old raspberry pico.
