Method put_cell

nodedb/src/engine/array/memtable/tile_buffer.rs:204–227

Insert a cell at `(coord, system_from_ms)`. The `system_from_ms` participates in the tile key so two writes at different system-time stamps produce two separate tile entries.

    /// system-time stamps produce two separate tile entries.
