Proposal: add support for ILogger (Microsoft.Extensions.Logging)

Since HttpClientFactory injects an ILogger and uses LogDebug to log requests and responses, it would be helpful to do the same with Dapper to log SQL statements. It could be a game changer when debugging!

Yep, definitely. That Dapper doesn't appear to have anything like the command interceptor in EF that allows easily logging the full SQL/parameter values when exceptions occur is a significant drawback.
