feat(trading-strategies): complete the running interval from minutes in BatchedIndicator.warmUp

[bennycode]

Builds on #1418, please merge that first.

When live candles start in the middle of an interval, say at 10:20 for hourly bars, the batcher only sees the minutes from 10:20 on. The first bar it completes is missing 10:00 to 10:19, so its open, high, low and volume are off.

warmUp() now takes the latest 1-minute candles as an optional second argument. Minutes after the last warm-up bar go through the batcher, so the running interval is complete when live candles take over. An interval that finished between the last warm-up bar and now goes to the indicator. Minutes the warm-up bars already cover are skipped, so nothing is counted twice.

hourly.warmUp(
  await market.getRecentCandles(pair, sma.getRequiredInputs(), ms('1h')),
  await market.getRecentCandles(pair, 60, ms('1m'))
);

The Getting Started example uses the new argument.
