v1.10.2 - Fix Access to Implementation Elements via EDIStreamReader

This bug fix release builds on release 1.10.1 to ensure that implementation composites/elements in a segment that occur prior to the discriminator element (identified in the schema) are properly made available to the EDIStreamReader via the getSchemaTypeReference method. It is a known issue that any implementation constraints for the elements will not be validated (to be fixed via #88 in a future release)

Change summary:
[ #87, #91 ] Update event array element types upon implementation segment selection
