feat(support) TypeORM

[feihan]

Hi,

this is a great library.
Unfortunately we are mostly using Typeorm (https://typeorm.io/) which is not supported yet.
I think this is one of the most important node.js ORMs currently.

If anyone is interested, i can try to help out as much as i can.

Thanks

You can see the early history TypeORM comment support at typeorm/typeorm#3643. In order to support sqlcommenter—even manually adding comments—TypeORM will need to be updated to affix comments to the end of the query instead of prefixing to the beginning.

After further testing I have determined that prefixed comments show up in the Cloud SQL tool as well as Datadog. My sampling rate was too low.
