calcPsyLevels(oneWeekMillis, showPsylevels, psyType, sydDST)
  calculate the psy levels
4 hour res based on how mt4 does it
mt4 code
int Li_4 = iBarShift(NULL, PERIOD_H4, iTime(NULL, PERIOD_W1, Li_0)) - 2 - Offset;
ObjectCreate("PsychHi", OBJ_TREND, 0, Time[0], iHigh(NULL, PERIOD_H4, iHighest(NULL, PERIOD_H4, MODE_HIGH, 2, Li_4)), iTime(NULL, PERIOD_W1, 0), iHigh(NULL, PERIOD_H4,
iHighest(NULL, PERIOD_H4, MODE_HIGH, 2, Li_4)));
so basically because the session is 8 hours and we are looking at a 4 hour resolution we only need to take the highest high an lowest low of 2 bars
we use the gmt offset to adjust the 0000-0800 session to Sydney open which is at 2100 during dst and at 2200 otherwize. (dst - spring foward, fall back)
keep in mind sydney is in the souther hemisphere so dst is oposite of when london and new york go into dst
  Parameters:
    oneWeekMillis: a constant value
    showPsylevels: should psy levels be calculated
    psyType: the type of Psylevels - crypto or forex
    sydDST: is Sydney in DST
return [psyHi, psyLo, psyHiLabel, psyLoLabel, psySessionStartTime]

  that calculates how much time is left until the next session taking the session start and end times into account. special case of intraday sessions like sydney
  Parameters:
    openToday: - timestamps of when the session opens in general - note its a series because the timestamp was created using the dst flag which is a series itself thus producing a timestamp series
