Improve crate 4.x support

[chicco785]

Since cratedb 4.0 timestamp is deprecated and may be removed any time soon. This update, provide timestamptz support for cratedb >= 4.0

Same applies to other data types we use:

• https://crate.io/docs/crate/reference/en/4.2/appendices/release-notes/4.0.0.html#general

Deprecated types have been aliased so nothing is going to break for the next couple of releases I'd imagine, but since we're at it, I suggest we take care of the other types too---string, long and not sure what else?

not a problem, but there is a substantial difference, timestamp generates billions of logs in crate, the others don't.

I saw the new commit, good stuff!

Shaw! I wonder why.
