Construct a 10-byte fixed-length binary field with an initial value of data.
@param data initial 10-byte binary value.  A null corresponds to zero value 
and does not affect the null-state (see {@link #setNull()} and {@link #isNull()}).
@param immutable true if field value is immutable
@throws IllegalArgumentException thrown if data is not 10-bytes in length
