Add minimum device version check

[jonnew]

Static device classes, e.g.

bonsai-onix1/OpenEphys.Onix1/ConfigureHeadstage64ElectricalStimulator.cs

Line 49 in 4fd9cb5

static class Headstage64ElectricalStimulator

Should contain a constant specifying the minimum require device version that is supported by the library. This has become a requirement since we have begun to implement gateware updates to devices since the this library has become public. In general, the minimum required version should be the lowest that is fully supported by the library. There should be an additional check added to these functions within ContextHelper.cs.

bonsai-onix1/OpenEphys.Onix1/ContextHelper.cs

Line 10 in 4fd9cb5

public static DeviceContext GetDeviceContext(this ContextTask context, uint address, Type expectedType)

bonsai-onix1/OpenEphys.Onix1/ContextHelper.cs

Line 25 in 4fd9cb5

public static DeviceContext GetDeviceContext(this DeviceInfo deviceInfo, Type expectedType)

(Not sure about second one, will need to think about it).
