Fix wrong remote:scale argument parsing

[vsonnier]

Fix the remote:scale argument processing, removed the erroneous definition of scalar in SoapyRemote defs. Fix problem seen in Cubic while testing pothosware/SoapyPlutoSDR#19.

Now that #65 is in master, selecting the CS12 with scale 2048 shows the right scale for local CF32.

Its documented as scalar too: https://github.com/pothosware/SoapyRemote/wiki

I think the getStreamArgsInfo() is just advertising it wrong. Its consistent everywhere else as scalar

Which leads to the question, which is better, scale or scalar?

@guruofquality Unless I got my English wrong, scalar just means number, one dimension opposed to vector which has many. scale means , well scale of a map, or range of any quantity so I vote for scale.

It probably comes more down to "mathematics" jargon.

• Scale as in "scale factory" sounds about right: https://en.wikipedia.org/wiki/Scale_factor
• And then scalar as in "scalar quantity" is also right: https://en.wikipedia.org/wiki/Scalar_(physics)
  The converter operation essentially "multiplies a vector of samples by a scalar quantity"

I will sleep on it :-P

For me as well versed but a non-native speaker (and btw mathematician) scalar sounds wrong. As Vincent quotes, scalar is just a number where scale hints at a proportion :)

Well I guess if mathematics says its a bug.. Updated the wiki too
