Pure-text parser for Studio 5000 L5K controller exports. Recognises
TAG/END_TAG, DATATYPE/END_DATATYPE, and PROGRAM/END_PROGRAM blocks,
strips (* ... *) comments, and tolerates multi-line entries + unknown
sections (CONFIG, MOTION_GROUP, etc.). Output records — L5kTag,
L5kDataType, L5kMember — feed L5kIngest which converts to
AbCipTagDefinition + AbCipStructureMember. Alias tags and
ExternalAccess=None tags are skipped per Kepware precedent.
AbCipDriverOptions gains an L5kImports collection
(AbCipL5kImportOptions records — file path or inline text + per-import
device + name prefix). InitializeAsync merges the imports into the
declared Tags map, with declared tags winning on Name conflicts so
operators can override import results without editing the L5K source.
Tests cover controller-scope TAG, program-scope TAG, alias-tag flag,
DATATYPE with member array dims, comment stripping, unknown-section
skipping, multi-line entries, and the full ingest path including
ExternalAccess=None / ReadOnly / UDT-typed tag fanout.
