MCC XOP: Make the meter functions available

The following functions are in AxMultiClampMsg.h but are not exposed in the MCC XOP:

//==============================================================================================
// MCC Meter functions
//==============================================================================================

// Set resistance meter enable
AXMCCMSG BOOL WINAPI EXPORT MCCMSG_SetMeterResistEnable(HMCCMSG hMCCmsg, BOOL bEnable, int *pnError);

// Get resistance meter enable
AXMCCMSG BOOL WINAPI EXPORT MCCMSG_GetMeterResistEnable(HMCCMSG hMCCmsg, BOOL *pbEnable, int *pnError);

// Set Irms meter enable
AXMCCMSG BOOL WINAPI EXPORT MCCMSG_SetMeterIrmsEnable(HMCCMSG hMCCmsg, BOOL bEnable, int *pnError);

// Get Irms meter enable
AXMCCMSG BOOL WINAPI EXPORT MCCMSG_GetMeterIrmsEnable(HMCCMSG hMCCmsg, BOOL *pbEnable, int *pnError);

// Get the specified meter value in SI units
AXMCCMSG BOOL WINAPI EXPORT MCCMSG_GetMeterValue(HMCCMSG hMCCmsg, double *pdValue, UINT uMeterID, int *pnError);

Start with the meter function declarations in AxMultiClampMsg.h, then locate the MCC XOP entry points that expose the existing MCCMSG functions. Confirm how the five listed meter functions are registered and exposed, and verify that the completed XOP makes each function available.
