feat: ✨ pico ground station for micrometer launch

[ayecptn]

Description

For testing the rec_zephyr.py has to be slightly edited:

SM_UPDATE_FMT = "<IBBBB7dffBBBB"
...
def queue_frame(ftype, mv, plen, crc_ok):
    tag = "OK " if crc_ok else "BAD"
    if ftype == HC12_TYPE_SM_UPDATE and plen == SM_UPDATE_LEN and crc_ok:
        # float lat, float lon, uint8_t sats, uint8_t h, uint8_t m, uint8_t s
        (ts, state, armed, sm_type, _resv,
         altitude, accel, accel_vert, velocity,
         yaw, pitch, roll, lat, lon, sats, h, m, s) = struct.unpack_from(SM_UPDATE_FMT, mv, 0)
        states = SM_STATE_TABLES.get(sm_type)
        name = (states[state] if states and state < len(states)
                else "?%d" % state)
        tname = SM_TYPE_NAMES.get(sm_type, "?%d" % sm_type)
        out_lines.append(
            "[OK ] SM[%s] t=%d ms  state=%-9s armed=%d  alt=%+.2f  "
            "a=%+.2f  av=%+.2f  v=%+.2f  ypr=%+.2f/%+.2f/%+.2f "
            "lat=%f lon=%f sat=%s %s:%s:%s"
            % (tname, ts, name, armed, altitude, accel, accel_vert,
               velocity, yaw, pitch, roll, lat, lon, sats, h, m, s))
    else:
        out_lines.append("[%s] type=0x%02x len=%d" % (tag, ftype, plen))
