support sspi

[amhuhn2]

I have an Express app and need to use SSPI to connect to PG. Currently, I'm using password authentication, but this is against company policy. (Because of the need to store the password).

Hey @amhuhn2 - if SSPI is something your company needs but doesn't currently exist in the library I'm available to contract & implement this feature.

Otherwise, as always, I'm happy to review pull requests & add them if everything looks good! If you'd like to discuss contracting more please email me: brian.m.carlson@gmail.com. Thanks!
