Support for MSSQL named pipe (np:) and shared memory (lpc:) DSNs

[fsiler]

Hello, the Microsoft go-mssqldb module supports lpc: and np: DSNs. Could we get support for that here please? I'd like to use with sql_exporter and have raised this issue there as well.

I was not aware of these. I'll aim to add this to the next version of dburl and usql. Thanks for pointing this out. I will need to think what the "right" way to do this is, but likely it will take the form of sqlserver+lpc:// and sqlserver+np:// style URLs, as this is used with other databases that support different protocol transports (ie, TCP vs UDP).
