daylight savings shifts are out of sync

[Mark Lewis]

for the sessions function, it would be better to specify the open and close time natively to the timezone that we are targeting using the pytz format. eg:

smc.sessions(df, 'New York', '09:30', '16:00', timezone= "America/New_York")

This is because the daylight savings shifts for each country is not in sync, which means that twice a year, there will be several weeks where New York is in daylight savings, but London isn't or vice versa. The same can be said of other timezones.
