feat(go): add validation suite

[Mandukhai-Alimaa]

What's Changed

Setup validation suite and override tests

Closes #6 .

7 tests are failing. Not sure how to handle them. @lidavidm can you take a look? Thanks

I locked my account...I'll test later

#42 It seems one of the internal queries needs updating.

#43 I think we need to sort the result by ordinal_position.

I think this is a known issue with how Snowflake treats timestamp types on ingest. We should just mark this as the "correct" answer for now.

Invalid bind value (+Inf) for type (REAL).. Vendor code: 2086. SQLSTATE: 22000

I'm not sure where this is coming from. Maybe Snowflake sees very large doubles as Inf?

#44 I think this is a bug.

[lidavidm]

Can you fix the float64 and ingest timestamp issues? For float64 maybe change the data being bound, for ingest timestamp just mark it as expected that the result type is different

[Mandukhai-Alimaa]

Fixed the float64 and ingest timestamp issues and fixed the driver name too. For float64 binding, it dont seem to accept anything larger than 1.797693e+38.

[lidavidm]

Why are these coming back as LA time?

[Mandukhai-Alimaa]

Snowflake is returning these in the session timezone. I set the session timezone to UTC and removed the LA time overrides.
