Sessions end point query filters

[k1o0]

Currently there's no easy way to obtain e.g. n_trials from alyx without listing a load of sessions then individually querying each returned url. Could there be a way to specify the which fields to return in the endpoint? e.g. /sessions?n_trials= would return the n_trials field in addition. If not, could we perhaps have a full sessions endpoint in addition to the 'light' one we currently have?
