Delete data for an interval after each power-up event

This trims the spurious data that instruments can produce for a short time interval after each power-on events.

deleteStartupData(
  x,
  gapTime = 60,
  deleteTime = 20,
  stream = "payload1",
  debug = getOption("gliderDebug", default = 0)
)

`x`	an [oceglider-class] object, e.g. as read by 'read.read.glider.seaexplorer.raw()' or similar functions.
`gapTime`	numeric value, in seconds, used to infer power-on events. There is always one event at the start of the time series. In addition, any time differences that exceed 'startupCriterion' seconds are considered to be power-off events, so the first time after such an interval is taken to be a power-on event.
`deleteTime`	numeric value indicating the time interval, in seconds, of data that will be removed.
`stream`	character value naming the stream to use, if the object is multi-streamed, meaning that the 'data' slot contains multiple data frames, one for the glider (named 'glider') another for the first payload (named '"payload"'), and possibly other payloads. The value of 'stream' is ignored unless the object's 'metadata' slot contains an item named 'dataAreStreamed' and that item is TRUE.
`debug`	an integer, less than or equal to zero for no message, and positive to print information about the processing.
