In cpp_message several fields can cause overflows from assignment to uint values during MIN/MAX checks

[willjohnsonk]

Summary

There are cases in certain cpp_message where a field uses a uint type to set a temporary variable to check against internal min/max values but this assignment can cause those values to overflow before the check occurs. Consider assigning these temporary fields to a more flexible type (long, double) prior to doing the check.

Version

4.3.0 (Current)

Expected Behavior

An incoming value that is larger/smaller than the MIN/MAX as defined in the ASN.1 message definition should be clamped to the MIN/MAX and raise an warning.

Actual Behavior

If an incoming value that is larger than the defined MAX and assigned to a uint type smaller than that max the value will overflow on assignment and not update or raise a warning.

Steps to Reproduce the Actual Behavior

Create an input test message with test data larger than the max value represented by a field that uses a temporary uint variable to check MAX/MIN adherence
