Add new Non Adaptive temporal modes similar to `time.precision.mode=connect`

It is easier to handle non variable-precision time values in the consumers.

Similar to current current `time.precision.mode=connect` option, Precision should be extended if lower and dropped if its greater than the given setting

Options:

• time.precision.mode=milliseconds
• time.precision.mode=microseconds
• time.precision.mode=nanosecond
• time.precision.mode=isostring (ISO-8601 formatted string)
