Only call SetVSAmplitude if the camera supports it.

[MarkRivers]

Commit 5e34010 from @pheest added code that unconditionally calls SetVSAmplitude. This fails on cameras that don't support that call.

@pheest is there a way to determine if SetVSAmplitude is supported on a given camera, and skip that block if it is?

See #48 for some details.

Sorry about that. I will address the issue as soon as I can, should be within a couple of days. The call that’s required is ‘GetCapabilities’, it outputs a list of capabilities (including vertical shift speed and amplitude selection) that are available for some Andor camera models, but not others. Our spectroscopists typically use this capability to frame transfer at the highest possible speed, in order to minimise light smearing.

The required code fragment would be:
if ((mCapabilities.ulSetFunctions & AC_SETFUNCTION_VSAMPLITUDE) != 0)
{
asynPrint(this->pasynUserSelf, ASYN_TRACE_FLOW,
"%s:%s:, SetVSAmplitude(%d)\n",
driverName, functionName, verticalShiftAmplitude);
checkStatus(SetVSAmplitude(verticalShiftAmplitude));
}
