Summary

Refine IB adapter

• Allow to use any venue or exchange when using IB as data and execution client (see example notebook)
• Refactored instrument provider to work better, especially when converting exchanges to MIC venues or vice versa. The key idea is to always provide a venue or exchange as argument to related functions in order to avoid uncertainty on what to use.
• Removed Databento symbology option, it works with IB simplified instead and convert_exchange_to_mic_venue in InteractiveBrokersInstrumentProviderConfig

instrument_provider = InteractiveBrokersInstrumentProviderConfig(
    symbology_method=SymbologyMethod.IB_SIMPLIFIED,
    convert_exchange_to_mic_venue=True,
)

• Modified supported futures and options on futures symbols to be compatible with databento (single digit for years and space between underlying and option specification).
• Moved set_specific_venue to cache instead of portfolio, so account_for_venue returns a consistent result throughout the system
• Add support for priceMagnifier, the nautilus side is unmagnified, and the conversion to and from IB is handled in various places of the code
• Fixed support for contfut for historical bars. Thanks to @FGU1 for additional ideas to make the solution more elegant.
• added possibility to request ibcontract information (load_id) for all instruments already in the cache, loaded from a catalog for example. Possibility also to avoid an IB call if the IB contract details are already saved in the catalog and present in an already loaded instrument.
