Remap non-std IB exhcange values

Add exchange name translation in `.ib.venues.has_holiday()` to handle
non-standard exchange codes when looking up holiday gaps..

Deats,
- add an ad-hoc lookup dict to remap an IB `Contract.primaryExchange` val
  which doesn't exist in the `exchange_calendars`'s alias set.
- use `.get()` with fallback to map `exch` to new `std_exch` and pass
  that to `xcals.get_calendar()`.
- add the case i just caught, `'ARCA'` -> `'ARCX'` to the table when i loaded
  the `gld.arca.ib` market..
