Jonny Elliott 6979ae8d6a ENH: fast stochastic oscillator added (#1255)
ENH: fast stochastic oscillator added.

A fast stochastic oscillator has been added to the technical
factors. This is the simplest of the stochastic oscillators,
and can be used to build the others.

Tests have been added that compare against the values expected
from that of ta-lib STOCHF.

FastStochasticOscillator is marked as window_safe=True to allow taking
moving averages for smoothing.

Eddie Hebert e75c4650b0 MAINT: Remove unused data conversion script.
The file format converted by this script has no support for reading in
Zipline. Remove since it requires import of a library not defined in
requirements.

datashape should be optional, this ensures it is actually optional.

Andrew Daniels 8e6c98e9aa BUG: Fixes reading and writing of daily bars first_trading_day attr
When writing first_trading_day, it is already in the correct frame of
reference (seconds since epoch) and does not need to be transformed
further. Adjusts the reader to expect this value.

Andrew Daniels 71f12ec272 MAINT: Adds first_trading_day arg to DataPortal
Instead of inferring it from the minute/daily writer, we now require the
first trading day to be passed explicitly, so the creator of the
DataPortal controls what is used as the first trading day.

Eddie Hebert 2f80e94203 TST: Enable sourcing daily data from minute data.
Allow `WithBcolzDailyBarData` to opt-in to reading data defined by
`WithBcolzMinuteBarData`, so that the daily and minute test for the same
asset and dts correlate between the two readers.
The correlation is relevant for history tests which blend daily and
minute data.

Also, make the test data for the split and mergers assets in the minute
suite align at the thousands place if the adjustmets are applied
correctly, by starting the prices with a base of 4000 and then halving
the start value each day.

Andrew Daniels f1cfe1f2db BUG: Fixes bcolz padding to not always pad 390 minutes
If minutes already exist for the last existing day, adjust the number of
minutes padded to account for them. Previously we would always pad 390,
leading to a mismatch in the number of rows.

Joe Jevnik 163ba8d76d ENH: remove the ffill lower bound query in blaze loader
This query is often only cutting out a couple of months or a week of
data. The cost of computing this lower bound does not outway the cost of
sending back too much data.

Joe Jevnik 2d36a58add ENH: improve performance of time comparisons
Adds `mask_time_between` to do more efficient comparisons between
pandas.DatetimeIndex and datetime.time objects.

This is used in the loader utils to more efficiently normalize datetimes
around the query time.
