Inconsistent generic recogniser APIs

[atruskie]

Is your feature request related to a problem? Please describe.

The various generic recogniser APIs have some inconsistent parameters. We should clean these up.

Describe the solution you'd like

All the following APIs were identified by looking at references: most are only referenced in tests and not actually used or are duplicates of the newer PostProcessing stage. None of the following are hard requirements - if any of these are wrong, then strike them out. Seeking feedback.

• [ ] Remove: UpwardTrackParameters.CombineProximalSimilarEvents
• [ ] Remove: UpwardTrackParameters.SyllableStartDifference
• [ ] Remove: UpwardTrackParameters.SyllableHertzDifference
• [ ] Remove: ForwardTrackParameters.CombinePossibleSyllableSequence
• [ ] Remove: OnebinTrackParameters.CombinePossibleSyllableSequence
• [ ] Rename: OnebinTrackParameters (to HorizontalTrackParameters? WhistleParameters? Add an alias for both?)
• [ ] Rename: UpwardTrackParameters (to SlopingTrackParameters? WhipParameters? Add an alias for both?)
• [ ] Rename/Alias: VerticalTrackParameters (to Click?)
• [ ] Remove: UpwardTrackParameters.CombineProximalSimilarEvents¹
• [ ] Remove: UpwardTrackParameters.SyllableStartDifference¹
• [ ] Remove: UpwardTrackParameters.SyllableHertzDifference¹
• [ ] Remove: OneframeTrackParameters.CombineProximalSimilarEvents (currently commented out)

(1) Actually used by algorithm, though still duplicates of PostProcessing parameters

... more to come...

For all renames: keep previous YamlTypeTag attribute for backwards combability. e.g.

+[YamlTypeTag(typeof(WhistleParameters))]
[YamlTypeTag(typeof(OnebinTrackParameters))]
+public class WhistleParameters: CommonParameters
-public class OnebinTrackParameters : CommonParameters
{
}
