`array_vacuum()` with timestamps sets consolidation timestamps

[cgiachalis]

array_vacuum() has optional arguments to set time stamps but these affect consolidation time stamps. See source code further below.

Note that sm.vacuum.timestamp_start and sm.vacuum.timestamp_end are not listed in Academy's consolidation-and-vacuuming neither are found looking at config params tiledb::config(tiledb::tiledb_get_context()); but it seems are being used in Python client here; also Python's consolidation definition erroneously defines vacuum timestamps here.

Lastly, checking config params at C++ docs, there is no definitions for sm.vacuum.mode, sm.vacuum.timestamp_start, sm.vacuum.timestamp_end here.

body(tiledb::array_vacuum)

{
    stopifnot(`Argument 'uri' must be character` = is.character(uri))
    if (is.null(cfg)) {
        cfg <- config(ctx)
    }
    if (!missing(start_time)) {
        stopifnot(`Argument 'start_time' must be datetime object` = inherits(start_time, 
            "POSIXt"))
        start_time_int64 <- bit64::as.integer64(as.numeric(start_time) * 
            1000)
        cfg["sm.consolidation.timestamp_start"] <- as.character(start_time_int64) # <-------------------- HERE
    }
    if (!missing(end_time)) {
        stopifnot(`Argument 'end_time' must be datetime object` = inherits(end_time, 
            "POSIXt"))
        end_time_int64 <- bit64::as.integer64(as.numeric(end_time) * 
            1000)
        cfg["sm.consolidation.timestamp_end"] <- as.character(end_time_int64) # <-------------------- HERE
    }
    ctx <- tiledb_ctx(cfg)
    libtiledb_array_vacuum(ctx = ctx@ptr, uri = uri, cfgptr = cfg@ptr)
}
