Improve Import DMA Channels

[rdecarreau]

The Import DMA Channel feature is super convenient but has issues.
There is no documentation about the format.
There should be an "Export DMA Channels" button.
Shouldn't this also import/export the Delacing Scheme, dt, Mode, Update Rate and DMA Host Buffer?

You are welcome to update the documentation here:
Source\Help\HTML Help Source\DMA Channel.html

You are welcome to add an export.

I would not add the other items because they can change with FPGAs. The export/import is ideally agnostic of FPGA programming.

That makes sense. I will restrict to just the channels themselves.
Is the html help the preferred method, or are we moving to a README based help?

HTML is currently the preferred method. We are going to move to Readme in the future but aren't there yet.
