Write orientation & transform in C++ (#1637)
* locationd at 20hz * update ref * bump cereal * dont modify global state * add scons files * ecef2geodetic and geodetic2ecef * Finish local coords class * Add header file * Add orientation.cc * cleanup * Add functions to header file * Add cython wrapper * y u no work? * This passes the tests * test rot2quat and quat2rot * Teste euler2rot and rot2euler * rot_matrix * test ecef_euler_from_ned and ned_euler_from_ecef * add benchmark * Add test * Consistent newlines * no more radians supported in geodetic * test localcoord single * test localcoord single * all tests pass * Unused import * Add alternate namings * Add source for formulas * no explicit tests needed * remove benchmark * Add release files * Typo * Remove print statement * no access to raw transform matrix * temporarily add tolerance * handcode quat2euler * update ref
