Epic L (live/incremental) of cellpy 2.2 (Stage 5). Design: live-incremental §3.
Add the optional loader capability in cellpy (not cellpycore — the contract is only between loaders and CellpyCell.update(); core's update_data never sees it):
@runtime_checkable class SupportsIncrementalLoad(Protocol): load_since(source, marker) -> IncrementalChunkLoadMarker (last source_datapoint_num / byte_offset / row_count) and IncrementalChunk (new_raw, marker, complete)
Marker semantics match core update_data (new_raw may overlap the tail; overlap trimmed on source_datapoint_num). Loaders that can't do cheap partial reads simply don't implement it → update() falls back to full reload.
