This handles better for BLOB type columns. Without this, it basically would have only worked for ASCII binary data since it gets Buffer.toString()'d, but then does an extra quoting and sanitization pass.

For binary data, which we can assume is coming from a Uint8Array, we want to send as hexadecimal.

Fixes #161

Ok, the fundamental issue with this solution is that Buffer is specific to node and doesn't exist for all JS runtimes.

I think we need to do something to deal with this as an ArrayBuffer or Uint8Array ?

I'm not sure if we can feature-detect and allow Buffer when that's available globally or not.

We should be able to add some trivial unit tests for this to confirm behavior.

I think we want to handle empty strings when it's binary data and not just return an empty string
