Create symbols for common diodes

[seveibar]

Some of these can probably be removed if they're super uncommon or don't have a symbol

• Create symbol for zener_diode #57
• Create symbol for light_emitting_diode
• Create symbol for schottky_diode #58
• Create symbol for laser_diode #59
• Create symbol for varactor_diode #60
• Create symbol for tunnel_diode #84
• Create symbol for photodiode #61
• Create symbol for avalanche_diode #83
• Create symbol for pin_diode #118
• Create symbol for pn_junction_diode #119
• Create symbol for step_recovery_diode #120
• Create symbol for gunn_diode #121
• Create symbol for rectifier_diode #122
• Create symbol for super_barrier_diodes #123
• Create symbol for small_signal_diode #124
• Create symbol for transient_voltage_suppressor_diode #125
• Create symbol for constant_current_diode #126
• Create symbol for silicon_controlled_rectifier
