This is a really rough start to a port of libpredict to Arduino platform. Currently only known working MCU is Arm Cortex-M0 (Adafruit Feather M0)
- No SDP4 support (focus on near nearth objects)
- Contains change from la1k/libpredict#79 due to lack of
time(NULL)
support on Cortex-M0 (it is semihosted).
