LW20 / SF20 LiDAR sensor

Data streaming
The LW20 can stream up to five read commands (?).
Set a stream using the format: <$><stream num><,><parameter name><CR>
For example:
To stream the median distance to the first return, on stream one: $1,ldf<CR>
To stream the signal strength of first return, on stream two: $2,lhf<CR>
You can clear an individual stream by using: $<stream num><CR>
You can clear all streams by sending!$<CR>
Streams are considered a settable parameter like any other in the LW20, therefore you can save the stream to persist through boot
up. The command!%p<CR>!will save all settings.
Note: Saving parameters in the LW20 happens on flash memory, which has limited writes. This is not a problem for everyday use, but
don't call the save command in a tight loop, as you could exhaust the flash if you accidentally call it a few hundred thousand times.
