ENH: Pass calendar instance to BcolzMinuteBarWriter (#1406)

* First pass.

* Improvements and fixes

- Update usages of BcolzMinuteBarWriter
- Updates with rebuilt example data
- Expose calendar from BcolzMinuteBarMetadata instead of calendar_name
- Keep market_opens and market_closes in metadata for compatibility

* Store start_session and end_session in minute bcolz metadata

- start_session replaces first_trading_day
- Add end_session to limit to correct days

* For last_available_dt, get last close from calendar to maintain tz

* Bumps version and handles earlier versionson read

* Rebuilt example data on python 3

* Indicate metadata fields that are deprecated
