Joseph Doherty ce98c2ada3 Auto: s7-a4 — array tags (ValueRank=1) ...

- S7TagDefinition gets optional ElementCount; >1 marks the tag as a 1-D array.
- ReadOneAsync / WriteOneAsync: one byte-range Read/WriteBytesAsync covering
  N × elementBytes, sliced/packed client-side via the existing big-endian scalar
  codecs and S7DateTimeCodec.
- DiscoverAsync surfaces IsArray=true and ArrayDim=ElementCount → ValueRank=1.
- Init-time validation (now ahead of TCP open) caps ElementCount at 8000 and
  rejects unsupported element types: STRING/WSTRING/CHAR/WCHAR (variable-width)
  and BOOL (packed-bit layout) — both follow-ups.
- Supported element types: Byte, Int16/UInt16, Int32/UInt32, Int64/UInt64,
  Float32, Float64, Date, Time, TimeOfDay.

Closes #290
