Some contracts missing in option_chain

[valankar]

Describe the bug There appears to be some contracts that show up on the Yahoo website but not when querying with yahooquery.

To Reproduce

https://finance.yahoo.com/quote/%5ESPX/options/?date=1742515200&strike=5900

shows SPX250321C05900000:

https://finance.yahoo.com/quote/SPX250321C05900000/

But when querying this:

>>> option_chain = yahooquery.Ticker('^SPX').option_chain
>>> option_chain.loc[lambda df: df["contractSymbol"] == 'SPX250321C05900000']
Empty DataFrame
Columns: [contractSymbol, strike, currency, lastPrice, change, percentChange, openInterest, bid, ask, contractSize, lastTradeDate, impliedVolatility, inTheMoney, volume]
Index: []
>>> option_chain.loc[lambda df: df["contractSymbol"].str.startswith('SPX250321C059')]
                                  contractSymbol  strike currency  lastPrice     change  percentChange  openInterest    bid    ask contractSize       lastTradeDate  impliedVolatility  inTheMoney  volume

Expected behavior 5900 strike price should show up above, but it only starts from 5905.
