dsIsAsync: Asynchronous result support

In DSI: 'DataSHIELD' Interface

Asynchronous result support

Description

When a DSResult-class object is returned on aggregation or assignment operation, the raw result can be accessed asynchronously, allowing parallelization of DataSHIELD calls over multpile servers. The returned named list of logicals will specify if asynchronicity is supported for: aggregation operation ('aggregate'), table assignment operation ('assignTable'), resource assignment operation ('assignResource') and expression assignment operation ('assignExpr').
