CSV Parser to allow mix of unit of measure in the same file

Right now, we have successfully tested handling of unit conversion if "frame of reference" information is provided in File meta data. Such as when the dataset is registered for the source CSV file. With this arrangement, all values of MD, TVD, ELEVATION columns will be considered as "ft".

We propose enhancement so that unit of measure can be another column an source CSV can have mix of data, some in "m" and some in "ft" inside the same file.

                        "name": "ft",
                        "persistableReference": "{\"scaleOffset\":{\"scale\":0.3048,\"offset\":0.0},\"symbol\":\"ft\",\"baseMeasurement\":{\"ancestry\":\"Length\",\"type\":\"UM\"},\"type\":\"USO\"}",
                        "propertyNames": [
                            "MD",
