[Changelog] teltonika protocol

For FMB640 series:

1. remastered parsing of Tell Tale statuses based on this documentation
   

2. several settings renamed:
   battery_voltage_io_640 => battery_voltage_io
   battery_level_io_640 => battery_level_io
   inputs1_fmb640 => inputs1
   analog_input1_io_640 => analog_input1_io
   analog_input2_io_640 => analog_input2_io
   axis_x_640 => axis_x
   axis_y_640 => axis_y
   axis_z_640 => axis_z
   inputs2_fmb640 => inputs2
   inputs3_fmb640 => inputs3
   inputs4_fmb640 => inputs4

3. bugfix in parsing of ID 255: now the value is stored to parameter overspeeding.speed. If the value is higher than overspeeding limit set in overspeeding_dout3 setting, then the parameter overspeeding.status = true stored, otherwise overspeeding.status = false stored

New device type FTM305 added
