Add in-place EBCDIC processor that converts data to VRL format

[yruslan]

Background

Currently, the EBCDIC in-place record processor does not allow changing record size because it preserves the original format, including all headers. But if we allow conversion to variable-record-length format (with RDWs), record sizes can be changed as part of transformations

Feature

Add in-place EBCDIC processor that converts data to VRL format.
