Import extra_fields #25
Description
Is your feature request related to a problem? Please describe.
Cannot use extra_fields functionality as documented.
Describe the solution you'd like
I would like to be able to use extra_fields when working with CSV data, allowing access to additional columns beyond the standard OHLCV data.

from pynecore.lib import ta, Series, close, extra_fields
def main():
some_price: Series[float] = extra_fields["some_price"]
realtime_some_price = some_price[0]
confirmed_some_price = some_price[1]
some_price_ma = ta.sma(some_price, 7)
some_flag: Series[bool] = extra_fields["some_flag"]
...Describe alternatives you've considered
Currently using the volume column as a workaround (though it's limited to integers float only).
Additional context
Thank you for creating such an excellent library.
This feature would greatly enhance the flexibility of CSV data processing workflows.
