Commit Message

PERF: Optimize session close lookups in resample bar reader (#1749)

Optimize session close lookups in MinuteResampleSessionBarReader:

- Adds `session_closes_in_range` method (along with
  `session_opens_in_range`) to TradingCalendar to allow vectorized
  retrieval of all values in a range of sessions.
- Improves code path for resampling a single session's worth of data (as
  is the case when calling `get_value`), since we don't actually need to
  look up the close minute.
