Drop the "not yet implemented / BadNotSupported" stale note from all three
S7 CLI --type option descriptions (ReadCommand, WriteCommand, SubscribeCommand)
and replace with accurate help listing the full supported type set, byte-anchored
addressing for wide types, and Timer/Counter read-only status.
docs/v2/driver-specs.md §5: add Supported Data Types table, Byte-Anchored
Addressing table (DBB/MB/IB/QB + examples), Timer/Counter read section with
the Counter-BCD known-limitation, and Deferrals list.
docs/drivers/S7.md: expand Data types to a full table, add "Wide types &
Timer/Counter" section (byte-anchored addressing, Timer/Counter read-only,
Counter BCD known-limitation, deferrals), update Address forms table and
1-D array Deferrals note.
