adjusted

Switches the request to TIME_SERIES_MONTHLY_ADJUSTED, whose bars carry an adjusted close and a dividend amount alongside the raw prices.

This sets the endpoint only. Reading the extra fields back also needs the response parser to be told the payload is adjusted, which TimeSeries.monthly().adjusted() does on the caller's behalf — a builder used directly returns a payload the plain com.crazzyghost.alphavantage.timeseries.response.TimeSeriesResponse parser will not read the adjusted fields out of.
